Description
CATO manufactures 25-Hydroxycholesterol-26,26,26,27,27,27-d6 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.
CATO supplies 25-Hydroxycholesterol-26,26,26,27,27,27-d6 (CAS 88247-69-2), a certified reference material (molecular formula C27H40D6O2, MW 408.69 g/mol) for analytical method development and quality control.
Owing to deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage, 25-Hydroxycholesterol-26,26,26,27,27,27-d6 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 408.69 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
