Chemical Structure
Description
Owing to deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage, 4β-Hydroxy Cholesterol-d is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 406.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
4β-Hydroxy Cholesterol-d (CAS 1363529-44-5), molecular formula C27H42D4O2 and molecular weight 406.68 g/mol, is a CATO reference standard with documented purity and traceability.
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 manufactures 4β-Hydroxy Cholesterol-d under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
