About Tolfenamic Acid

Listed under CAS 13710-19-5, Tolfenamic Acid is a high-purity reference standard of Tolfenamic acid available from Vaqora Chemicals. Its molecular formula is C14H12ClNO2 and its molecular weight is 261.7 g/mol. The IUPAC name is 2-(3-chloro-2-methylanilino)benzoic acid. Common synonyms include Acido tolfenamico and Acide tolfenamique.

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 “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Laboratories use this Tolfenamic acid 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.
