Estrone Sulfate

About Estrone Sulfate

Estrone Sulfate is a high-purity reference standard of Estrone carrying the CAS registry number 481-97-0. Its molecular formula is C18H22O5S and its molecular weight is 350.4 g/mol. Alternative names: Estrone 3-sulfate and Estrone Sulphate.

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. Good laboratory practice and suitable PPE are recommended during handling.

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