Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 22(S)-hydroxycholesterol-d7.
22(S)-hydroxycholesterol-d7 (CAS 1246302-91-9) is a high-purity analytical reference standard with the molecular formula C27H39D7O2 and a molecular weight of 409.70 g/mol.
Owing to deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage, 22(S)-hydroxycholesterol-d7 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 409.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures 22(S)-hydroxycholesterol-d7 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.
