About Resmethrin

Listed under CAS 10453-86-8, Resmethrin is an API reference standard available from Vaqora Chemicals. Its molecular formula is C22H26O3 and its molecular weight is 338.4 g/mol. The IUPAC name is (5-benzylfuran-3-yl)methyl 2,2-dimethyl-3-(2-methylprop-1-enyl)cyclopropane-1-carboxylate. Alternative names: For-syn and Benzofuroline.

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 “Warning”, 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. It is used across pharmaceutical manufacturing and academic and industrial research.

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