Description
CATO manufactures 5-Bromo-3-chloro-1-methyl-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.
5-Bromo-3-chloro-1-methyl-1H-indazole (CAS 1243459-17-7), molecular formula C8H6BrClN2 and molecular weight 245.50 g/mol, is a CATO reference standard with documented purity and traceability.
5-Bromo-3-chloro-1-methyl-1H-indazole (C8H6BrClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/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.
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.
