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 3-(6-Chloro-2-methyl-3-oxo-2,3-dihydro-4H-benzo[b][1,4]oxazin-4-yl)propanoic acid (CAS 501911-22-4), a certified reference material (molecular formula C12H12ClNO4, MW 269.68 g/mol) for analytical method development and quality control.
3-(6-Chloro-2-methyl-3-oxo-2,3-dihydro-4H-benzo[b][1,4]oxazin-4-yl)propanoic acid (C12H12ClNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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 3-(6-Chloro-2-methyl-3-oxo-2,3-dihydro-4H-benzo[b][1,4]oxazin-4-yl)propanoic acid 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.
