Pipemidic Acid

About Pipemidic Acid

Pipemidic Acid is a high-purity reference standard of Pipemedic acid carrying the CAS registry number 51940-44-4. Its molecular formula is C14H17N5O3 and its molecular weight is 303.32 g/mol. Systematically, it is named 8-ethyl-5-oxo-2-piperazin-1-ylpyrido[2,3-d]pyrimidine-6-carboxylic acid. Alternative names: Acido pipemidico and Acide pipemidique.

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 “Danger”, so handle it with suitable PPE and consult the SDS.

Laboratories use this Pipemedic acid standard for identity and assay testing, system suitability checks and method validation supporting ANDA and DMF filings. 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.
