About Tropicamide EP Impurity A

Listed under CAS 33403-97-3, Tropicamide EP Impurity A is a pharmacopeial impurity of Benzoic acid available from Vaqora Chemicals. With the molecular formula C8H12N2, it has a molar mass of 136.19 g/mol. Its systematic (IUPAC) name is N-(pyridin-4-ylmethyl)ethanamine. Alternative names: 4-(Ethylaminomethyl) Pyridine and Tropicamide - Impurity A.

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.

Pharmaceutical QC and development laboratories use this impurity standard of Benzoic acid to develop and validate HPLC methods, to set specification limits and to document impurity profiles in ANDA and DMF submissions. 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.
