Estradiol Benzoate EP Impurity G (CAS 2393-53-5) is a pharmacopeial impurity of Estradiol benzoate offered by Vaqora Chemicals. The compound has the formula C25H26O3, corresponding to a molecular weight of 374.5 g/mol. Its systematic (IUPAC) name is [(8R,9S,13S,14S)-13-methyl-17-oxo-7,8,9,11,12,14,15,16-octahydro-6H-cyclopenta[a]phenanthren-3-yl] benzoate. Common synonyms include Estradiol Benzoate - Impurity G and Estrone benzoate.

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

Pharmaceutical QC and development laboratories use this impurity standard of Estradiol benzoate 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.
