1, (5α)-CHOLESTEN-3-ONE CAS 566-44-9 chemical structure

Description

CATO supplies 1, (5α)-CHOLESTEN-3-ONE (CAS 566-44-9), a certified reference material (molecular formula C27H46O, MW 386.65 g/mol) for analytical method development and quality control.

Structurally, 1, (5α)-CHOLESTEN-3-ONE (C27H46O) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 386.65 g/mol, it falls into the moderately-high-molecular-weight range. 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).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
