Chemical Structure
Description
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.
5-Bromo-4-(trifluoromethyl)-1H-indazole (CAS 1385821-29-3), molecular formula C8H4BrF3N2 and molecular weight 265.03 g/mol, is a CATO reference standard with documented purity and traceability.
5-Bromo-4-(trifluoromethyl)-1H-indazole (C8H4BrF3N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution. Halogen substitution raises its density and boiling point; 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-4-(trifluoromethyl)-1H-indazole 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.
