Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Bromo-1H-pyrido[2,3-d][1,3]oxazin-2(4H)-one.
CATO supplies 6-Bromo-1H-pyrido[2,3-d][1,3]oxazin-2(4H)-one (CAS 335032-38-7), a certified reference material (molecular formula C7H5BrN2O2, MW 229.03 g/mol) for analytical method development and quality control.
Based on its molecular formula C7H5BrN2O2, 6-Bromo-1H-pyrido[2,3-d][1,3]oxazin-2(4H)-one contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 229.03 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
