About Epicatechin Gallate

Listed under CAS 1257-08-5, Epicatechin Gallate is an API impurity reference standard available from Vaqora Chemicals. Formula C22H18O10, molecular weight 442.4 g/mol. Its systematic (IUPAC) name is [(2R,3R)-2-(3,4-dihydroxyphenyl)-5,7-dihydroxy-3,4-dihydro-2H-chromen-3-yl] 3,4,5-trihydroxybenzoate. It is also known as Epicatechin-3-galloyl ester or (-)-Epicatechin-3-O-gallate.

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. 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.
