CATO supplies 3-(2,6-Dichlorophenyl)-5-methyl-N-(thiazol-2-yl)isoxazole-4-carboxamide (CAS 326902-99-2), a certified reference material (molecular formula C14H9Cl2N3O2S, MW 354.21 g/mol) for analytical method development and quality control.
The molecular framework of 3-(2,6-Dichlorophenyl)-5-methyl-N-(thiazol-2-yl)isoxazole-4-carboxamide (C14H9Cl2N3O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
