Chemical Structure
Description
The occurrence of Cortisone-d8 (Major) is closely related to deuterium isotope labeling, a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Cortisone-d8 (Major) (CAS CATO-CCAD302953), a certified reference material (molecular formula C21H20D8O5, MW 368.49 g/mol) for analytical method development and quality control.
Structurally, Cortisone-d8 (Major) (C21H20D8O5) contains deuterium isotope labeling, a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 368.49 g/mol, it falls into the moderately-high-molecular-weight range. 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), Cortisone-d8 (Major) 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.
