About O-Desmethylangolensin

O-Desmethylangolensin is a metabolite or degradation product of Conjugated estrogens carrying the CAS registry number 21255-69-6. Its molecular formula is C15H14O4 and its molecular weight is 258.27 g/mol. Systematically, it is named 1-(2,4-dihydroxyphenyl)-2-(4-hydroxyphenyl)propan-1-one. Common synonyms include O-Demethylangolesin and 2,4-Dihydroxyphenyl p-hydroxyphenethyl ketone.

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. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Analytical teams use this compound to identify metabolites and degradants of Conjugated estrogens, to validate stability-indicating methods (AMV) and to support QC and regulatory filings. It is used across pharmaceutical manufacturing and academic and industrial research.

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