About Cyproterone Acetate

Cyproterone Acetate (CAS 427-51-0) is a high-purity reference standard of Cyproterone offered by Vaqora Chemicals. The compound has the formula C24H29ClO4, corresponding to a molecular weight of 416.9 g/mol. Alternative names: Cyproterone 17-O-acetate and SH 714.

The product is provided 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 “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

As a reference sample of Cyproterone, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

We offer Cyproterone Acetate in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
