Description
264273-08-7 [(1S)-4-Amino-1-{[(9H-fluoren-9-yl)methoxy]carbonyl}-3-oxo-1,3,4,5-tetrahydro-2H-2-benzazepin-2-yl]acetic acid DTXSID30725193 (CAS 264273-08-7), molecular formula C27H24N2O5 and molecular weight 456.49 g/mol, is a CATO reference standard with documented purity and traceability.
264273-08-7 [(1S)-4-Amino-1-{[(9H-fluoren-9-yl)methoxy]carbonyl}-3-oxo-1,3,4,5-tetrahydro-2H-2-benzazepin-2-yl]acetic acid DTXSID30725193 (C27H24N2O5) contains a steroid core, 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.
