About Ospemifene

Ospemifene (CAS 128607-22-7) is a high-purity reference standard of Ospemifene offered by Vaqora Chemicals. Formula C24H23ClO2, molecular weight 378.9 g/mol. The IUPAC name is 2-[4-[(Z)-4-chloro-1,2-diphenylbut-1-enyl]phenoxy]ethanol. Alternative names: FC-1271a and Deamino-hydroxytoremifene.

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. Under GHS it is labelled “Warning”, so handle it with suitable PPE and consult the SDS.

As a reference sample of Ospemifene, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. 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.
