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 7-CHloro-1h-pyrido[2,3-b][1,4]oxazin-2-ol.
CATO supplies 7-CHloro-1h-pyrido[2,3-b][1,4]oxazin-2-ol (CAS 2065250-37-3), a certified reference material (molecular formula C7H5ClN2O2, MW 184.58 g/mol) for analytical method development and quality control.
Based on its molecular formula C7H5ClN2O2, 7-CHloro-1h-pyrido[2,3-b][1,4]oxazin-2-ol contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 184.58 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
