Chemical Structure

15beta-hydroxycholestene 26660-51-5 CAS 26660-51-5 chemical structure

Description

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.

15beta-hydroxycholestene 26660-51-5 (CAS 26660-51-5) is a high-purity analytical reference standard with the molecular formula C27H46O2 and a molecular weight of 402.65 g/mol.

The molecular framework of 15beta-hydroxycholestene 26660-51-5 (C27H46O2) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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.
