CATO supplies 6-Bromo-7-(2-chloroacetyl)-2h-benzo[b][1,4]oxazin-3(4h)-one (CAS 1094432-20-8), a certified reference material (molecular formula C10H7BrClNO3, MW 304.52 g/mol) for analytical method development and quality control.
6-Bromo-7-(2-chloroacetyl)-2h-benzo[b][1,4]oxazin-3(4h)-one (C10H7BrClNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 6-Bromo-7-(2-chloroacetyl)-2h-benzo[b][1,4]oxazin-3(4h)-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.
