5a-Pregnane-3a,20a-diol CAS 566-58-5

Description

Compared with other compounds in its class, the molecular weight of 320.51 g/mol gives 5a-Pregnane-3a,20a-diol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5a-Pregnane-3a,20a-diol (CAS 566-58-5) is a high-purity analytical reference standard with the molecular formula C21H36O2 and a molecular weight of 320.51 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, 5a-Pregnane-3a,20a-diol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 320.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
