Chemical Structure
Description
The occurrence of Etravirine D4 is closely related to deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Etravirine D4 (CAS 1142095-93-9), molecular formula C20H11D4BrN6O and molecular weight 439.30 g/mol, is a CATO reference standard with documented purity and traceability.
Etravirine D4 (C20H11D4BrN6O) contains deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Etravirine D4 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.
