Chemical Structure

3-O-Benzyl 16-Epiestriol CAS 33116-58-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 378.50 g/mol gives 3-O-Benzyl 16-Epiestriol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-O-Benzyl 16-Epiestriol (CAS 33116-58-4) is a high-purity analytical reference standard with the molecular formula C25H30O3 and a molecular weight of 378.50 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, 3-O-Benzyl 16-Epiestriol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 378.50 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 3-O-Benzyl 16-Epiestriol 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.
