Chemical Structure
Description
Owing to deuterium isotope labeling, a flavonoid core, a hydroxyl group, an ether linkage, 5α-tetrahydrocortisol d5 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 371.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 5α-tetrahydrocortisol d5 (CAS 252976-07-1), a certified reference material (molecular formula C21H29D5O5, MW 371.52 g/mol) for analytical method development and quality control.
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), 5α-tetrahydrocortisol d5 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.
