CATO supplies 5-(5-Bromo-2-methylphenyl)-1,2,4-oxadiazole-3-carboxylic acid (CAS 1468984-99-7), a certified reference material (molecular formula C10H7BrN2O3, MW 283.08 g/mol) for analytical method development and quality control.
5-(5-Bromo-2-methylphenyl)-1,2,4-oxadiazole-3-carboxylic acid (C10H7BrN2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
