Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-Bromo-3-(4-chlorophenyl)benzo[c]isoxazole (CAS 887-90-1) is a high-purity analytical reference standard with the molecular formula C13H7BrClNO and a molecular weight of 308.56 g/mol.
5-Bromo-3-(4-chlorophenyl)benzo[c]isoxazole (C13H7BrClNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
CATO manufactures 5-Bromo-3-(4-chlorophenyl)benzo[c]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.
