Chemical Structure

(24S)-24-Methylcholest-8(14)-ene CAS 6673-69-4 chemical structure

Description

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.

CATO supplies (24S)-24-Methylcholest-8(14)-ene (CAS 6673-69-4), a certified reference material (molecular formula C28H48, MW 384.68 g/mol) for analytical method development and quality control.

The molecular framework of (24S)-24-Methylcholest-8(14)-ene (C28H48) is characterized by an aromatic ring system. 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).

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.
