Dichlorvos

About Dichlorvos

Dichlorvos is an API reference standard carrying the CAS registry number 62-73-7. Its molecular formula is C4H7Cl2O4P and its molecular weight is 220.97 g/mol. The IUPAC name is 2,2-dichloroethenyl dimethyl phosphate. It is also known as 2,2-Dichlorovinyl dimethyl phosphate or Nerkol.

It is supplied as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Laboratories use this the parent drug substance standard for identity and assay testing, system suitability checks and method validation supporting ANDA and DMF filings. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

We offer Dichlorvos in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
