How do I check if my SDS for 2,3-epoxypropyl methacrylate is still valid?

When dealing with a document about 2,3-epoxypropyl methacrylate that is already in use, the primary concern should be verifying its accuracy rather than immediately considering replacement. If inaccuracies are found, it is essential to identify the specific sections requiring correction. Errors frequently appear across multiple documents; thus, reviewing three documents can often yield insights that would otherwise necessitate examining three hundred.

Sensitisation and declaration thresholds

Sensitisation (H317) carries consequences beyond the label: a threshold for declaring the substance in mixtures far below the general cut-off, and — where the entry is on the candidate list — an obligation to inform recipients. Importers frequently discover this at the point where a customer asks for a declaration they had not prepared.

Purity, certificates and what the sheet does not say

A laboratory receiving 2,3-epoxypropyl methacrylate from its supplier holds two documents that must agree with each other: the safety data sheet for the substance and the certificate for the batch in hand. Where identity or supplier details diverge between them, both become questionable. MolGod prepares and audits those documents; the material itself comes from your supplier.

Which GHS pictograms apply to 2,3-epoxypropyl methacrylate?

The label for 2,3-epoxypropyl methacrylate carries GHS05 (corrosion), 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 106-91-2, 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 is the EC number for 2,3-epoxypropyl methacrylate?

Alongside CAS 106-91-2, this substance carries EC number 203-441-9 and Annex VI index 607-[CAS?]. 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.

How is 2,3-epoxypropyl methacrylate classified for road, sea and air transport?

Section 14 for CAS 106-91-2 carries the UN number, proper shipping name, class, packing group and environmental hazard where these apply. Where the substance is not dangerous for carriage, the section says so explicitly rather than being left empty — an empty section 14 reads as an omission, not as an absence of hazard.

Protective equipment and exposure controls

Section 8 outlines exposure controls and personal protective equipment (PPE) for 2,3-epoxypropyl methacrylate: appropriate glove materials, eye protection, respiratory protection when warranted by the hazard classification, and any established occupational exposure limits. The choice of glove material is more critical than merely wearing gloves; nitrile gloves are not universally suitable.

What is the CLP classification of 2,3-epoxypropyl methacrylate?

The harmonised classification for CAS 106-91-2 carries 10 hazard statements: H350, H341, H360F, H311, H302, H335, H372 (inhalation) (respiratory tract), H314, H318, H317. In plain terms this means may cause cancer; suspected of causing genetic defects; may damage fertility; toxic in contact with skin. 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.

Other names for this substance

The same substance appears in trade and in the literature under several names: glycidyl methacrylate. A safety data sheet has to carry the name used in the harmonised entry, but a purchase order, a customs declaration and a certificate of analysis may each use a different one. Where the names diverge, CAS 106-91-2 is the identifier that reconciles them — and a document set that relies on trade names alone will eventually be read as describing three different materials.

Is 2,3-epoxypropyl methacrylate classified as a CMR substance?

CAS 106-91-2 is classified as a CMR substance (H350, H360F). That status changes the obligations attached to every shipment: workplace exposure documentation, restrictions on supply to the general public, and substitution pressure from downstream users who must justify continued use. A safety data sheet for a CMR substance is read more closely than any other, because the classification itself invites scrutiny.

Which SDS sections decide whether a shipment clears?

A sheet for CAS 106-91-2 is read by number, not as a narrative. Subsections matter as much as sections: an inspector looking for 3.1 will not accept the information folded into a paragraph elsewhere, however complete that paragraph is. Completeness is judged by structure first and content second.

Who is responsible for REACH compliance for 2,3-epoxypropyl methacrylate?

The responsibility for documentation accompanying 2,3-epoxypropyl methacrylate lies with the entity introducing it into the Union market, rather than with any external supplier. Importers bear the same obligations as manufacturers, including designating an identifiable EU contact in section 1. A non-EU supplier may appoint a sole representative, but this appointment must be established prior to the movement of goods, not in response to subsequent inquiries.

Can I import 2,3-epoxypropyl methacrylate into the EU?

An import of CAS 106-91-2 is successful or unsuccessful based on whether the accompanying document matches the register entry. Among carboxylic acid esters, a common failure arises from classification carried over from a supplier outside the Union, where the same substance may be classified differently. The binding reference is index 607-[CAS?], and discrepancies occur in solvent and intermediate shipments.

What Annex VI notes and concentration limits apply to 2,3-epoxypropyl methacrylate?

The Annex VI entry for CAS 106-91-2 carries note D. Notes are not commentary: they modify how the classification applies — to concentration ranges, to specific forms of the substance, or to the labelling that follows from it. An entry read without its notes is read incompletely.

Where is regulatory status recorded for 2,3-epoxypropyl methacrylate?

The existence of additional obligations beyond classification for CAS 106-91-2, such as inclusion in the candidate list, authorisation, or restrictions, should be addressed in section 15. As customers increasingly require a written statement regarding these obligations prior to placing an order, this section serves as the appropriate location to provide clarity on the matter.

Identifiers that must agree

Identity is checked before hazard. If the label, the sheet and the certificate disagree about what CAS 106-91-2 is called, or if index 607-[CAS?] points somewhere the name does not, a reviewer stops trusting all three documents at once, even though each was internally consistent.

What must the label for 2,3-epoxypropyl methacrylate contain?

The supply label for 2,3-epoxypropyl methacrylate 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 H350, H341, H360F… 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.

Accidental release and containment

A spill of CAS 106-91-2 is handled from section 6, which has to state the containment material and the protective equipment needed to approach. A sheet that describes cleanup without stating what to wear while doing it is incomplete.

Questions about documentation for 2,3-epoxypropyl methacrylate

What is the CAS number of 2,3-epoxypropyl methacrylate?

CAS 106-91-2. In CLP Annex VI the same substance carries index number 607-[CAS?], and both identifiers should appear in the documentation.

Is 2,3-epoxypropyl methacrylate a CMR substance?

Yes. The harmonised classification places it among substances classified as carcinogenic, mutagenic or toxic for reproduction, which changes workplace documentation and supply restrictions.

What hazard statements apply to CAS 106-91-2?

The harmonised entry lists H350, H341, H360F, H311. 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 2,3-epoxypropyl methacrylate is placed on the market, unless that State has stated otherwise.
