methanol (CAS 67-56-1) — Safety Data Sheet

EU · SVHCUS · TSCACA · NDSLAU · AICSMolGod评分：主要

Safety data sheet documentation for methanol (CAS 67-56-1), compiled to REACH Annex II with classification read against the harmonised entry in CLP Annex VI (H225, H331, H311, H301). Two options: a working draft sent by e-mail immediately, or a signed card issued within 72 hours of complete input. The item supplied is a document — MolGod.org does not sell, supply or ship chemical substances.

Free, and generated automatically from the sources listed on this page. No person has reviewed it, and it describes the substance in general — not your material, your process or your intended market.

您将收到的内容 — 以及这不是什么

您将收到的内容

  • 一份数字 PDF 安全数据表，采用 REACH 附件 II（法规 1907/2006）规定的十六部分结构。
  • 物质标识、危害分类、理化、毒理学和生态学信息以及法规参考。
  • 如该物质在 CLP 附件 VI 中有统一分类条目，则依据该条目核对分类。
  • 版本号、编制日期，以及每个附有来源的数值所依据的来源。
  • 通过电子邮件交付，不寄送任何实物。

这不是什么

  • 不是化学物质，不是样品，也不是任何实物商品。
  • 这不是认证。欧盟不存在针对安全数据表的官方认证制度。
  • 不构成法律批准，也不保证在任何司法管辖区合规。
  • 不能替代您自己的法规评估，也不能替代您实际持有物质的制造商或进口商提供的安全数据表。
  • 除非您提供相关信息，否则不针对特定工作场所、工艺或国家附录进行调整。

当现有证据不足以支持某一数值时，数据表会注明该数值未确定，而不是进行估算。没有记录来源的字段会被如实标注。

买方资料包包含哪些内容

您的合规专员会要求的一切，集中在一个文件中。

  • PDF 格式的产品页面 — 与发布内容一致的记录，确保您转发的内容与您阅读的内容相符。
  • 与您权限级别相应的安全数据表 — 按 REACH 附件 II 规定顺序排列的十六个部分，针对该物质，采用您选择的语言。
  • CLP 标签设计稿 — 与安全数据表基于同一分类生成，因此两者不可能互相矛盾。
  • 规格书，以及在有批次数据时提供的分析证书。
  • sources.txt — 每条引用均注明查阅日期。
  • 我们无法确定事项的明确清单 — 相关字段标注为“不可用”，而不是用估计值填充。这是文件中诚实的部分，我们不会把它藏在脚注里。

您的欧洲买方会把这些资料转发给没有参加通话的人。资料包的意义在于，让其转发的内容完整、不言自明且可追溯 — 而不是四个附件加一句以 “我想就这些了” 开头的话。

Every version, including the Chinese one, is written to EU law — (EC) No 1907/2006 (REACH) Annex II and (EU) 2020/878 — and translated from it. The Chinese version is a reference translation, not a legally valid document for the Chinese market: an SDS for China must be compiled separately to GB/T 16483 and GB/T 17519.

Two guarantees, both with their limits stated

The Gap Report Guarantee

If the available evidence cannot support a defensible document for your CAS number and product specification, we will not invent the missing values. You receive a documented gap report and choose: a refund, store credit, or the report on its own.

A visible gap is worth more than a plausible number, because the plausible number is the one that fails when somebody checks it.

The Re-issue Promise

If a signed card is rejected by an authority or by a customer’s compliance officer on one of the points we checked and reported as passed, we re-issue it corrected at no charge and credit the original fee.

This covers the checks we performed and named. It does not cover registration status, tonnage, or your role in the supply chain — those are not ours to hold, and a guarantee that pretended otherwise would be worth nothing.

methanol — CAS 67-56-1, Annex VI index 603-001-00-X. Below: what the regulatory file for this substance must contain and where such files usually fail.

methanol (CAS 67-56-1) at a glance

  • Substance – methanol
  • CAS number – 67-56-1
  • EC number – 200-659-6
  • CLP Annex VI index number – 603-001-00-X
  • Hazard statements – H225 (highly flammable liquid and vapour); H331 (toxic if inhaled); H311 (toxic in contact with skin); H301 (toxic if swallowed); H370 (causes damage to organs)
  • Hazard classes – Flam. Liq. 2, Acute Tox. 3 *, Acute Tox. 3 *, Acute Tox. 3 *, STOT SE 1
  • Label pictograms – GHS02, GHS06, GHS08
  • Signal word – Danger
  • Concentration limits / M-factor / ATE – *;STOT SE 1;H370: C ≥ 10.0%;STOT SE 2;H371: 3.0% ≤ C < 10.0%
  • Entry current as of – CLP00
  • CMR classification – not classified as CMR in the harmonised entry
  • Documentation issued – safety data sheet in REACH Annex II structure; working draft or signed card
  • What is supplied – a document. MolGod.org does not sell, supply or ship chemical substances.

What concentration limits apply to methanol?

The harmonised entry for methanol carries specific concentration limits: H370: C≥10 %; H371: 3 % ≤ C<10 %. These override the generic cut-off values, so a mixture containing methanol is classified against these figures and not against the default thresholds.

Is methanol on the SVHC candidate list?

Outside the Union the same substance appears on AICS (AU), NDSL (CA), TSCA (US). Exporters are read against the list of the destination, not of the origin.

What is the UN number for methanol?

For carriage, methanol is assigned UN 1230, transport class 3, packing group II, with subsidiary risk 6.1. These entries belong in section 14 of the safety data sheet and must match the shipping papers exactly. A consignment where the sheet and the transport document disagree on the UN number is stopped before anyone reads the remaining fifteen sections.

What Annex VI notes and concentration limits apply to methanol?

The register also records *;STOT SE 1;H370: C ≥ 10.0%;STOT SE 2;H371: 3.0% ≤ C < 10.0% for this entry. Specific concentration limits, M-factors and acute toxicity estimates override the generic cut-off values, so a mixture calculation that ignores them will classify the mixture wrongly in both directions.

Protective equipment and exposure controls

Laboratories building a risk assessment for methanol start from section 8. Where an occupational exposure limit exists it must be stated with its source and averaging period; where none exists, the sheet says so rather than leaving the field blank.

Is methanol a controlled substance?

Storage requirement on record: Annex XVII entry 69: ≤0.6% in windscreen-washer/defroster fluids supplied to general public. None of this appears in the CLP classification, so a sheet built from Annex VI alone will be silent on it.

Which GHS pictograms apply to methanol?

The label for methanol carries GHS02 (flame), GHS06 (skull and crossbones), GHS08 (health hazard), with the signal word Danger. These are not chosen by the supplier: CLP Annex VI states them for CAS 67-56-1, and the precedence rules in Annex I decide which pictogram is dropped when two would say the same thing. A label showing a different set from the register is wrong even if every hazard statement on it is correct.

What must the label for methanol contain?

The supply label for methanol is generated from the same classification that drives the safety data sheet: pictograms selected by precedence, one signal word derived from the highest hazard class present, and the hazard statements H225, H331, H311… reproduced in full. Where the container is too small to carry the complete set at a legible size, there are lawful ways to handle it and unlawful ones that look identical to a non-specialist.

Disposal route and waste classification

Section 13 for CAS 67-56-1 outlines the disposal method and procedures for contaminated packaging. Laboratories are subject to audits to ensure their waste management practices align with the information provided in this section. Any ambiguity or lack of specificity in this section may result in findings against the laboratory rather than the supplier, as it is responsible for adhering to the declared waste stream.

What is the EC number for methanol?

Alongside CAS 67-56-1, this substance carries EC number 200-659-6 and Annex VI index 603-001-00-X. European documentation is built around the EC number as often as around the CAS: registration dossiers, the candidate list and customs systems key on it. A safety data sheet quoting only one of the two forces every downstream reader to look up the other.

What is the CLP classification of methanol?

The harmonised classification for CAS 67-56-1 carries 5 hazard statements: H225, H331, H311, H301, H370. In plain terms this means highly flammable liquid and vapour; toxic if inhaled; toxic in contact with skin; toxic if swallowed. A harmonised entry is binding across the Union — an importer may not soften it, and a self-classification that diverges from it will not survive an enforcement check.

Published sources behind the data

The toxicological and physicochemical record for methanol rests on published literature, not on a supplier summary. One of the canonical references is BASF / Mittasch, A.; Pier, M. (1923), “Synthesis of methanol from CO and H2 (BASF high-pressure process patent)”, German Patent DE 415686. Where a value in the sheet comes from a specific paper, the sheet says which paper — a reviewer can then check one number without re-reading the whole document.

How is methanol classified for road, sea and air transport?

Carriers and forwarders handling methanol compare section 14 against the shipping papers before loading. Any disagreement stops the consignment at the point where correcting it is most expensive.

Identifiers that must agree

Three identifiers travel with this substance and all three have to agree: CAS 67-56-1, the Annex VI index number 603-001-00-X, and the name as it appears in the register. Mismatched identifiers are the quietest defect in a documentation set, because every individual document looks correct and only a cross-check reveals that they describe different things.

Is methanol restricted under REACH Annex XVII?

Methanol is covered by entry 69 of Annex XVII to REACH, which restricts how it may be placed on the market or used. A restriction is not the same as a classification: it limits the permitted uses regardless of how the substance is labelled, and it belongs in section 15 of the sheet. Importers who read only the classification and stop there routinely miss this.

Questions about documentation for methanol

What hazard statements apply to CAS 67-56-1?

The harmonised entry lists H225, H331, H311, H301. These are binding across the Union and may not be softened by a self-classification.

In which language must the sheet be supplied?

In an official language of each Member State where methanol is placed on the market, unless that State has stated otherwise.

Can I check whether my existing sheet is still valid?

Yes. A section-by-section reading against Annex II and the current harmonised entry establishes that in one pass, and a sheet that passes is reported as passing.

Do I need a safety data sheet to import methanol into the EU?

Yes. A sheet compiled to Annex II of REACH must exist before the first consignment moves, and it must be held by the entity placing the substance on the Union market.

    机制： 乙醇是乙醇脱氢酶（ADH；Km ~ 1 mM，甲醇 ~ 7 mM）的优先底物。乙醇使 ADH 饱和，从而阻断甲醇转化为有毒的甲醛和甲酸。

    临床后果： 临床应用：乙醇是甲醇中毒的解毒剂（替代药物：甲吡唑）。不受控制地合用会掩盖逐渐加重的代谢性酸中毒。

    处理措施： 甲醇中毒时：乙醇 IV/PO 至血药浓度 100–150 mg/dL，或甲吡唑 15 mg/kg + 血液透析，由毒理学专家监护。

常见问题解答——关于PXRD
How does SCXRD differ from PXRD?
SCXRD (Single Crystal XRD) uses a single crystal and gives full three-dimensional structural data (atomic coordinates, bond lengths). PXRD uses a powder and gives a diffraction pattern. SCXRD is more accurate, but requires a good crystal. PXRD is faster, cheaper, and is used for phase identification, analysis of mixtures and quality control.
What is the 2θ angle in PXRD?
2θ is the angle between the incident beam and the diffracted beam, measured in degrees. Bragg's law (nλ = 2d·sinθ) relates the diffraction angle to the d-spacing between lattice planes. For Cu Kα (λ=1.54056 Å) typical peaks lie in the 5–70° range. Each peak corresponds to a different family of hkl planes.
How is the PXRD data from this accordion used in the laboratory?
Record the 2θ and I/I₀ values from the peak table. Measure the PXRD pattern of the sample on a powder diffractometer (Cu Kα). Compare peak positions to ±0.2° and the relative intensities. If at least 3 major peaks agree — the sample has an identical polymorphic form. Deviations > 0.5° may indicate a different form, contamination or lattice strain.
What is the Cambridge Structural Database (CSD)?
The CSD (Cambridge Structural Database) is a commercial CCDC database with 1.3 million organic and metal-organic structures — the gold standard of crystallography. Every structure has a unique refcode (e.g. ACSALA01 = aspirin Form I). Access requires a licence (~USD 5,775/year academic). WebCSD (searching individual structures) and Mercury (visualisation) are free.
