Estriol is a natural product carrying the CAS registry number 50-27-1, specified at 97% purity. With the molecular formula C18H24O3, it has a molar mass of 288.4 g/mol. The IUPAC name is (8R,9S,13S,14S,16R,17R)-13-methyl-6,7,8,9,11,12,14,15,16,17-decahydrocyclopenta[a]phenanthrene-3,16,17-triol. Common synonyms include 1,3,5(10)-Estratriene-3,16a,17ß-triol and 16a-Hydroxyestradiol.

In its supplied form it is a white to off-white powder. Literature values give a melting point of 280-282 °C. Store sealed in a dry, well-ventilated location away from incompatible materials. Under GHS it is labelled “Danger”, so handle it with suitable PPE and consult the SDS.

Key uses span phytochemical research, natural product screening and nutraceutical R and D. Buyers come mainly from academic and industrial research and diagnostics and biotechnology.

We offer Estriol in 100 mg, 500 mg, 1 g and 5 g packs with a batch-specific COA, and ship to customers worldwide.
