Chemical Structure
Description
2-[3-(2-bromophenyl)-1,2,4-oxadiazol-5-yl]benzoic acid (CAS 937665-29-7), molecular formula C15H9BrN2O3 and molecular weight 345.15 g/mol, is a CATO reference standard with documented purity and traceability.
2-[3-(2-bromophenyl)-1,2,4-oxadiazol-5-yl]benzoic acid (C15H9BrN2O3) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 2-[3-(2-bromophenyl)-1,2,4-oxadiazol-5-yl]benzoic 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.
