About 17beta-Dihydroequilin Sodium Sulfate

Vaqora Chemicals supplies 17beta-Dihydroequilin Sodium Sulfate, an impurity of Equilin registered under CAS number 16680-49-2. Its molecular formula is C18H21NaO5S and its molecular weight is 372.4 g/mol. Alternative names: 17-Beta-Dihydro Equilin 3-sodium Sulfate and 17β-Dihydro Equilin 3-Sulfate Sodium Salt.

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

Pharmaceutical QC and development laboratories use this impurity standard of Equilin 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.
