About Azafenidin

Azafenidin (CAS 68049-83-2) is an impurity of Ascorbic acid offered by Vaqora Chemicals. With the molecular formula C15H13Cl2N3O2, it has a molar mass of 338.2 g/mol. Systematically, it is named 2-(2,4-dichloro-5-prop-2-ynoxyphenyl)-5,6,7,8-tetrahydro-[1,2,4]triazolo[4,3-a]pyridin-3-one. Common synonyms include Azafenidin [ISO] and Milestone.

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. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

This Ascorbic acid impurity supports analytical method development and validation (AMV), batch release testing and the impurity sections of ANDA and DMF filings. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

We offer Azafenidin in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
