About Clemastine

Listed under CAS 15686-51-8, Clemastine is a high-purity reference standard of Clemastine available from Vaqora Chemicals. Its molecular formula is C21H26ClNO and its molecular weight is 343.9 g/mol. Its systematic (IUPAC) name is (2R)-2-[2-[(1R)-1-(4-chlorophenyl)-1-phenylethoxy]ethyl]-1-methylpyrrolidine. It is also known as Meclastin or Mecloprodin.

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. Handle it with standard laboratory precautions and appropriate personal protective equipment.

As a reference sample of Clemastine, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. Buyers come mainly from 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.
