Description

Compared with other compounds in its class, the molecular weight of 306.48 g/mol gives 1a-Methyl-5a-androstan-3a,17b-diol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1a-Methyl-5a-androstan-3a,17b-diol (CAS 4349-94-4) is a high-purity analytical reference standard with the molecular formula C20H34O2 and a molecular weight of 306.48 g/mol.

1a-Methyl-5a-androstan-3a,17b-diol (C20H34O2) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
