Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 399.42 g/mol gives 2,5-Dimethyl Celecoxib-d4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,5-Dimethyl Celecoxib-d4 (CAS 1346603-87-9), molecular formula C18H12D4F3N3O2S and molecular weight 399.42 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 2,5-Dimethyl Celecoxib-d4 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 399.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures 2,5-Dimethyl Celecoxib-d4 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
