Description
CATO supplies Etravirine-13C3 (CAS 1189671-48-4), a certified reference material (molecular formula C17[13C]3H15BrN6O, MW 438.25 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, Etravirine-13C3 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 438.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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-13C3 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.
