About Methomyl

Vaqora Chemicals supplies Methomyl, an API reference standard registered under CAS number 16752-77-5. Its molecular formula is C5H10N2O2S and its molecular weight is 162.21 g/mol. Systematically, it is named methyl N-(methylcarbamoyloxy)ethanimidothioate. It is also known as Methavin or 1-(Methylthio)ethylideneamino methylcarbamate.

The product is provided as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

As a reference sample of the parent drug substance, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. It is used across pharmaceutical manufacturing and academic and industrial research.

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