Chemical Structure
Description
(R)-3-Amino-5-methyl-2,3-dihydrobenzo[b][1,4]oxazepin-4(5H)-one (CAS 796038-22-7), molecular formula C10H12N2O2 and molecular weight 192.21 g/mol, is a CATO reference standard with documented purity and traceability.
(R)-3-Amino-5-methyl-2,3-dihydrobenzo[b][1,4]oxazepin-4(5H)-one (C10H12N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (R)-3-Amino-5-methyl-2,3-dihydrobenzo[b][1,4]oxazepin-4(5H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
