Chemical Structure

Cholesterol-23,24,25,26,27- CAS 150044-24-9 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.

CATO supplies Cholesterol-23,24,25,26,27- (CAS 150044-24-9), a certified reference material (molecular formula C22[13C]5H46O, MW 391.62 g/mol) for analytical method development and quality control.

Cholesterol-23,24,25,26,27- (C22[13C]5H46O) contains a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.

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.
