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 3,4-Dihydro-1,4-benzoxazine-3-one 6-oxoacetic Acid.
3,4-Dihydro-1,4-benzoxazine-3-one 6-oxoacetic Acid (CAS 1094428-30-4), molecular formula C10H7NO5 and molecular weight 221.17 g/mol, is a CATO reference standard with documented purity and traceability.
3,4-Dihydro-1,4-benzoxazine-3-one 6-oxoacetic Acid (C10H7NO5) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
