Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-Demethyl Mifepristone-d3 (CAS CATO-C4X-12165), molecular formula C28H30D3NO2 and molecular weight 418.59 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, N-Demethyl Mifepristone-d3 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 418.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), N-Demethyl Mifepristone-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.
