3-Amino-2,3-dihydrobenzo[b][1,4]oxazepin-4(5h)-one (CAS 94590-46-2), molecular formula C9H10N2O2 and molecular weight 178.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Amino-2,3-dihydrobenzo[b][1,4]oxazepin-4(5h)-one (C9H10N2O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
