About Prostaglandin B1

Prostaglandin B1 is a metabolite or degradation product of Alprostadil carrying the CAS registry number 13345-51-2. The compound has the formula C20H32O4, corresponding to a molecular weight of 336.5 g/mol. Systematically, it is named 7-[2-[(E,3S)-3-hydroxyoct-1-enyl]-5-oxocyclopenten-1-yl]heptanoic acid. Alternative names: PGB1 (Prostaglandin B1) and Prostaglandin E1-278.

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. Good laboratory practice and suitable PPE are recommended during handling.

Analytical teams use this compound to identify metabolites and degradants of Alprostadil, to validate stability-indicating methods (AMV) and to support QC and regulatory filings. 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.
