CATO supplies (2,4-Dichlorophenyl)(3-methyl-2,3-dihydro-4H-benzo[b][1,4]oxazin-4-yl)methanone (CAS 478043-15-1), a certified reference material (molecular formula C16H13Cl2NO2, MW 322.19 g/mol) for analytical method development and quality control.
Structurally, (2,4-Dichlorophenyl)(3-methyl-2,3-dihydro-4H-benzo[b][1,4]oxazin-4-yl)methanone (C16H13Cl2NO2) 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 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 322.19 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.
