Chemical Structure

24(R/S),25-epoxycholesterol-d6 CAS 1246302-86-2 chemical structure

Description

The occurrence of 24(R/S),25-epoxycholesterol-d6 is closely related to deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

24(R/S),25-epoxycholesterol-d6 (CAS 1246302-86-2), molecular formula C27H38D6O2 and molecular weight 406.67 g/mol, is a CATO reference standard with documented purity and traceability.

24(R/S),25-epoxycholesterol-d6 (C27H38D6O2) contains deuterium isotope labeling, 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.

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.
