Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 7-Bromo-2-methyl-3,4-dihydro-2H-benzo[b][1,4]oxazine (CAS 1245708-34-2), a certified reference material (molecular formula C9H10BrNO, MW 228.09 g/mol) for analytical method development and quality control.
7-Bromo-2-methyl-3,4-dihydro-2H-benzo[b][1,4]oxazine (C9H10BrNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 7-Bromo-2-methyl-3,4-dihydro-2H-benzo[b][1,4]oxazine 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.
