About Josamycin

Josamycin (CAS 16846-24-5) is a high-purity reference standard of Josamycin offered by Vaqora Chemicals. The compound has the formula C42H69NO15, corresponding to a molecular weight of 828.0 g/mol. It is also known as Leucomycin A3 or Turimycin A5.

It is supplied 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 “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

Laboratories use this Josamycin 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.

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.
