Chemical Structure

5α-ESTRAN-3α, 17β-DIOL CAS 10002-95-6 chemical structure

Description

Owing to a steroid core, a hydroxyl group, an ether linkage, 5α-ESTRAN-3α, 17β-DIOL is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 278.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

5α-ESTRAN-3α, 17β-DIOL (CAS 10002-95-6) is a high-purity analytical reference standard with the molecular formula C18H30O2 and a molecular weight of 278.43 g/mol.

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.
