Chemical Structure

3-O-Benzyl 15,16-Dehydro Estrone CAS 138743-03-0 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

3-O-Benzyl 15,16-Dehydro Estrone (CAS 138743-03-0), molecular formula C25H26O2 and molecular weight 358.47 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a hydroxyl group, an ether linkage, 3-O-Benzyl 15,16-Dehydro Estrone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 358.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO manufactures 3-O-Benzyl 15,16-Dehydro Estrone under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
