Chemical Structure
Description
Cortisol-9,12,12-d3 (CAS 115699-92-8) is a high-purity analytical reference standard with the molecular formula C21H27D3O5 and a molecular weight of 365.48 g/mol.
Owing to deuterium isotope labeling, a flavonoid core, a hydroxyl group, an ether linkage, Cortisol-9,12,12-d3 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 365.48 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.
As a certified reference material (CRM), Cortisol-9,12,12-d3 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.
