Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(2,6-Dichlorophenyl)-5-methyl-N-(5-methylisoxazol-3(2H)-ylidene)isoxazole-4-carboxamide.
CATO supplies 3-(2,6-Dichlorophenyl)-5-methyl-N-(5-methylisoxazol-3(2H)-ylidene)isoxazole-4-carboxamide (CAS 349613-77-0), a certified reference material (molecular formula C15H11Cl2N3O3, MW 352.17 g/mol) for analytical method development and quality control.
Structurally, 3-(2,6-Dichlorophenyl)-5-methyl-N-(5-methylisoxazol-3(2H)-ylidene)isoxazole-4-carboxamide (C15H11Cl2N3O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 352.17 g/mol, it falls into the moderately-high-molecular-weight range. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
