About Tropicamide EP Impurity B

Vaqora Chemicals supplies Tropicamide EP Impurity B, a pharmacopeial impurity standard registered under CAS number 57322-50-6. The compound has the formula C17H18N2O, corresponding to a molecular weight of 266.34 g/mol. The IUPAC name is N-ethyl-2-phenyl-N-(pyridin-4-ylmethyl)prop-2-enamide. Alternative names: Tropicamide Impurity B and Tropicamide - Impurity B.

It is supplied as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the 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 the parent drug substance 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.
