Pyriproxyfen

About Pyriproxyfen

Pyriproxyfen is an API reference standard carrying the CAS registry number 95737-68-1. With the molecular formula C20H19NO3, it has a molar mass of 321.4 g/mol. Its systematic (IUPAC) name is 2-[1-(4-phenoxyphenoxy)propan-2-yloxy]pyridine. It is also known as Pyriproxifen or Admiral.

It is supplied as a solid. Keep the vial tightly closed, protected from light and humidity, at the temperature stated on the Certificate of Analysis. Under GHS it is labelled “Warning”, so handle it with suitable PPE and consult the SDS.

Laboratories use this the parent drug substance standard for identity and assay testing, system suitability checks and method validation supporting ANDA and DMF filings. Our customers for this product work in pharmaceutical manufacturing and academic and industrial research.

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