Where is regulatory status recorded for chlorophacinone (ISO)?

Section 15 documents the regulatory status for chlorophacinone, detailing its inclusion on candidate lists, whether it is subject to authorisation or restriction, along with any applicable national regulations. This information is frequently requested by downstream users; providing a concise summary in a single document eliminates repetitive email exchanges with each customer.

Other names for this substance

The same substance appears in trade and in the literature under several names: 2-[(4-chlorophenyl)(phenyl)acetyl]-1H-indene-1,3(2H)-dione. 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 3691-35-8 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.

What Annex VI notes and concentration limits apply to chlorophacinone (ISO)?

The register also records Repr. 1B;H360D: C ≥ 0.003%;STOT RE 1;H372: C ≥ 0.1%;STOT RE 2;H373: 0.01% ≤ C < 0.1%;M = 1;M = 1 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.

Is chlorophacinone (ISO) classified as a CMR substance?

CAS 3691-35-8 is classified as a CMR substance (H360D). 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.

How is chlorophacinone (ISO) classified for road, sea and air transport?

Carriers and forwarders handling chlorophacinone must review section 14 in relation to the shipping documents prior to loading. If there are discrepancies, the shipment should be halted at the location where rectification would incur the highest cost.

How do I check if my SDS for chlorophacinone (ISO) is still valid?

Before ordering documentation for chlorophacinone (ISO), it is worth establishing whether the sheet already in use would survive an inspection. A section-by-section reading against Annex II and the harmonised entry answers that in a single pass, and where it passes, the honest outcome is that it passes.

In which language must the SDS for chlorophacinone (ISO) be supplied?

A safety data sheet must be supplied in an official language of every Member State where chlorophacinone (ISO) is placed on the market, unless that State has stated otherwise. This is the requirement most often missed by importers who hold a technically correct English document and assume it travels. A sheet in the wrong language is a refusal ground on its own, independent of the accuracy of its content.

What concentration limits apply to chlorophacinone (ISO)?

The harmonised entry for chlorophacinone carries specific concentration limits: H360D: C ≥ 0,003 %; H372 (blood): C ≥ 0,1 %; H373 (blood): 0,01 % ≤ C < 0,1 %. These override the generic cut-off values, so a mixture containing chlorophacinone is classified against these figures and not against the default thresholds. M-factor on record: 1. The M-factor multiplies the contribution of this substance in the aquatic hazard calculation for a mixture, which is where it is most often overlooked.

Which GHS pictograms apply to chlorophacinone (ISO)?

The label for chlorophacinone carries GHS06 (skull and crossbones), GHS08 (health hazard), GHS09 (environment), with the signal word Danger. These are not chosen by the supplier: CLP Annex VI states them for CAS 3691-35-8, 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.

Who is responsible for REACH compliance for chlorophacinone (ISO)?

The responsibility for documentation accompanying chlorophacinone (ISO) 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.

First-aid content and why it is read first

First-aid content for CAS 3691-35-8 has to be actionable by a person who is not a chemist and is reading under pressure. Section 4 also carries notes for the attending physician, which is where the classification becomes clinically relevant.

What is the EC number for chlorophacinone (ISO)?

Alongside CAS 3691-35-8, this substance carries EC number 223-003-0 and Annex VI index 606-[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.

Which SDS sections decide whether a shipment clears?

A sheet for CAS 3691-35-8 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.

Identifiers that must agree

Identity verification must be conducted prior to hazard assessment. If discrepancies exist between the label, safety data sheet, and certificate regarding the CAS 3691-35-8 number or if the index 606-[CAS?] refers to a location where the name does not match, a reviewer will lose trust in all three documents simultaneously, despite their internal consistency. This is because inconsistencies among these key documentation elements undermine their reliability as a unified source of information.

What is the CLP classification of chlorophacinone (ISO)?

The harmonised classification for CAS 3691-35-8 carries 7 hazard statements: H360D, H330, H310, H300, H372 (blood), H400, H410. In plain terms this means may damage the unborn child; fatal if inhaled; fatal in contact with skin; fatal 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.

Can I import chlorophacinone (ISO) into the EU?

Bringing chlorophacinone (ISO) into the Union is a documentation exercise before it is a logistics one. The file has to exist at the moment of import, not at the moment somebody asks for it, and for ketones it is examined in the context of solvent shipments. Index 606-[CAS?] fixes the classification that section 2 must reproduce.

Accidental release and containment

Section 6 addresses the accidental release of chlorophacinone, outlining personal precautions, environmental precautions, and containment methods. When the classification indicates an aquatic hazard, the environmental precautions section transitions from a mere formality to a critical instruction that must be rigorously followed.

What must the label for chlorophacinone (ISO) contain?

The supply label for chlorophacinone (ISO) 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 H360D, H330, H310… 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.

Questions about documentation for chlorophacinone

Do I need a safety data sheet to import chlorophacinone 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.

What is the CAS number of chlorophacinone?

CAS 3691-35-8. In CLP Annex VI the same substance carries index number 606-[CAS?], and both identifiers should appear in the documentation.

Is chlorophacinone 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 3691-35-8?

The harmonised entry lists H360D, H330, H310, H300. These are binding across the Union and may not be softened by a self-classification.
