About Sitostanol

Sitostanol (CAS 83-45-4) is a high-purity reference standard of Stigmasterol offered by Vaqora Chemicals. Its molecular formula is C29H52O and its molecular weight is 416.7 g/mol. Alternative names: Stigmastanol and Spinastanol.

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.

Laboratories use this Stigmasterol standard for identity and assay testing, system suitability checks and method validation supporting ANDA and DMF filings. Typical end-use sectors are 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.
