About Efaproxiral

Listed under CAS 131179-95-8, Efaproxiral is an API reference standard available from Vaqora Chemicals. Formula C20H23NO4, molecular weight 341.4 g/mol. Its systematic (IUPAC) name is 2-[4-[2-(3,5-dimethylanilino)-2-oxoethyl]phenoxy]-2-methylpropanoic acid. It is also known as 2-Dacmpp or RSR-13.

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. Good laboratory practice and suitable PPE are recommended during handling.

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. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
