7α-Hydroxy-4-cholesten-3-one-d7 (CAS CATO-C3D-2492) is a high-purity analytical reference standard with the molecular formula C27H37D7O2 and a molecular weight of 407.68 g/mol.
Owing to deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage, 7α-Hydroxy-4-cholesten-3-one-d7 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 407.68 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 7α-Hydroxy-4-cholesten-3-one-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.
