Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(4-Chlorophenyl)-2,3-dihydro-4H-benzo[e][1,3]oxazin-4-one.
CATO supplies 2-(4-Chlorophenyl)-2,3-dihydro-4H-benzo[e][1,3]oxazin-4-one (CAS 35141-49-2), a certified reference material (molecular formula C14H10ClNO2, MW 259.69 g/mol) for analytical method development and quality control.
2-(4-Chlorophenyl)-2,3-dihydro-4H-benzo[e][1,3]oxazin-4-one (C14H10ClNO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
