Safety Data Sheet
Getting an SDS for Sodium chloroacetate
A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of Sodium chloroacetate issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.
04 · Precautionary statements
Sodium chloroacetate precautionary statements
CLP Annex VI assigns 13 precautionary statements to Sodium chloroacetate. They are grouped the way a label groups them: what to do before handling, what to do when something has already happened, how to store it and how to dispose of it.
Prevention
What to do before and during handling so the hazard never happens.
Response
What to do once exposure, spillage or fire has already happened.
Disposal
What has to happen to the contents and the empty container.

05 · Names in the regulation
Sodium chloroacetate name in 23 EU languages
CLP Annex VI Part 3 is published in every language edition of the regulation, and the identification column is written out in each of them. Nothing below is translated by us: each line is the name as that edition prints it. Under Art. 18(2) the substance name from Annex VI is a lawful product identifier, so this is the wording to put on a label going to that market — and where the cell lists several designations, any one of them qualifies.

All 23 language editions of Annex VI carry this entry. Irish is the twenty-fourth official EU language and has no line here for a different reason: no consolidated CLP text has ever been published in Irish, so there is no Irish edition of Annex VI to quote a name from.

Sodium chloroacetate safe storage
Separated from food and feedstuffs and strong oxidants. Provision to contain effluent from fire extinguishing. Store in an area without drain or sewer access.

Sodium chloroacetate reactivity
Salts, basic, such as SODIUM CHLOROACETATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have pH's greater than 7.0. They react as bases to neutralize acids. These neutralizations generate heat, but less or far less than is generated by neutralization of the bases in reactivity group 10 (Bases) and the neutralization of amines. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible.

Sodium chloroacetate UN number and transport classification
Transport classification is a separate system from the GHS classification above. It decides how a package is marked and how a load may be carried; it does not follow from the workplace label, and the workplace label does not follow from it. The entries below are linked by CAS number, never by name.

11 · Questions
Sodium chloroacetate — frequently asked questions
What is the CAS number of Sodium chloroacetate?
The CAS number of Sodium chloroacetate is 3926-62-3. Its EC number is 223-498-3.
What is the chemical formula of Sodium chloroacetate?
The molecular formula of Sodium chloroacetate is C2H2ClNaO2 and its molecular weight is 116.48 g/mol.
What does a Sodium chloroacetate label have to show?
Under CLP Annex VI the label for Sodium chloroacetate carries the pictograms Skull and crossbones and Environment and the signal word is Danger.
Is Sodium chloroacetate flammable?
CLP Annex VI assigns Sodium chloroacetate no flammability hazard class. That is not a statement that it cannot burn: the harmonised list only records the hazards that were assessed for it.
Is Sodium chloroacetate a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for Sodium chloroacetate. Annex VI is a list of agreed classifications, not a list of substances found safe, so this is an absence of a classification rather than a clean bill of health.
