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 tert-Butyl (S)-(4-oxo-2,3,4,5-tetrahydropyrido[3,2-b][1,4]oxazepin-3-yl)carbamate.
tert-Butyl (S)-(4-oxo-2,3,4,5-tetrahydropyrido[3,2-b][1,4]oxazepin-3-yl)carbamate (CAS 2124262-62-8), molecular formula C13H17N3O4 and molecular weight 279.29 g/mol, is a CATO reference standard with documented purity and traceability.
tert-Butyl (S)-(4-oxo-2,3,4,5-tetrahydropyrido[3,2-b][1,4]oxazepin-3-yl)carbamate (C13H17N3O4) contains a nitrogen-containing heterocyclic scaffold, 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
