Description
CATO supplies 3-Amino-5-(4-bromophenyl)isoxazole (CAS 6525-98-0), a certified reference material (molecular formula C9H7BrN2O, MW 239.07 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H7BrN2O, 3-Amino-5-(4-bromophenyl)isoxazole contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 239.07 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 3-Amino-5-(4-bromophenyl)isoxazole 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.
