Chemical Structure
Description
7-Bromo-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazine hydrobromide (CAS 34968-20-2), molecular formula C7H7BrN2OHBr and molecular weight 295.96 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 7-Bromo-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazine hydrobromide (C7H7BrN2OHBr) contains an amide group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 295.96 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 7-Bromo-3,4-dihydro-2H-pyrido[3,2-b][1,4]oxazine hydrobromide 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.
