Description
As a certified reference material (CRM), (3β)-7-Dehydro Cholesterol-d7 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
(3β)-7-Dehydro Cholesterol-d7 (CAS 388622-58-0), molecular formula C27H37D7O and molecular weight 391.68 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C27H37D7O, (3β)-7-Dehydro Cholesterol-d7 contains deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 391.68 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
