Chemical Structure
Description
The occurrence of (S)-7-bromo-5-methyl-3-(tritylamino)-2,3-dihydrobenzo[b][1,4]oxazepin-4(5H)-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(S)-7-bromo-5-methyl-3-(tritylamino)-2,3-dihydrobenzo[b][1,4]oxazepin-4(5H)-one (CAS 2231663-34-4), molecular formula C29H25BrN2O2 and molecular weight 513.43 g/mol, is a CATO reference standard with documented purity and traceability.
(S)-7-bromo-5-methyl-3-(tritylamino)-2,3-dihydrobenzo[b][1,4]oxazepin-4(5H)-one (C29H25BrN2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
