2-(2,4-Dichlorophenyl)-7-methyl-4H-thieno[3,2-d][1,3]oxazin-4-one CAS 866151-46-4

Description

CATO supplies 2-(2,4-Dichlorophenyl)-7-methyl-4H-thieno[3,2-d][1,3]oxazin-4-one (CAS 866151-46-4), a certified reference material (molecular formula C13H7Cl2NO2S, MW 312.17 g/mol) for analytical method development and quality control.

Based on its molecular formula C13H7Cl2NO2S, 2-(2,4-Dichlorophenyl)-7-methyl-4H-thieno[3,2-d][1,3]oxazin-4-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 312.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
