Safety Data Sheet

Getting an SDS for Crotoxyphos

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 Crotoxyphos 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

Crotoxyphos precautionary statements

CLP Annex VI assigns 10 precautionary statements to Crotoxyphos. 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.

Disposal

05 · Names in the regulation

Crotoxyphos 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.

Crotoxyphos health hazards and exposure limits

Crotoxyphos hazard summary

A cholinesterase inhibitor; [Merck Index] No adverse effects to growth or histopathological changes were observed in 90 day feeding study with rats (males at 900 mg/kg diet and females 300 mg/kg diet); Cholinesterase inhibitor; [HSDB] The average of two baseline respective cholinesterase activity determinations three days apart, with no exposures to enzyme inhibiting pesticides for at least 30 days, is recommended for each worker prior to exposure to cholinesterase inhibitors because of large inter-individual differences in published baseline values. To be established at least once a year. Removal from workplace exposures is recommended until the cholinesterase activity returns to within 20% of baseline. [TLVs and BEIs]

Corrosivity

Slightly corrosive to copper, lead, mild steel, tin and zinc, but will not attack fiberglass, reinforced polyester, rigid PVC, or the usual lacquers used for lining drums. Incompatible with most mineral carriers, except synthetic silicas such as 'Colloidal Silica K320' and 'Hisil 233'.

Crotoxyphos — frequently asked questions

What is the CAS number of Crotoxyphos?

The CAS number of Crotoxyphos is 7700-17-6. Its EC number is 231-720-5.

What is the chemical formula of Crotoxyphos?

The molecular formula of Crotoxyphos is C14H19O6P and its molecular weight is 314.27 g/mol.

What does a Crotoxyphos label have to show?

Under CLP Annex VI the label for Crotoxyphos carries the pictograms Skull and crossbones and Environment and the signal word is Danger.

Is Crotoxyphos flammable?

CLP Annex VI assigns Crotoxyphos 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 Crotoxyphos a carcinogen?

CLP Annex VI records no harmonised carcinogenicity classification for Crotoxyphos. 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.

What is the boiling point of Crotoxyphos?

The boiling point reported for Crotoxyphos is 135 °C (275 °F), at 0.03 mmHg (reduced pressure) (HSDB).

How should Crotoxyphos be stored?
