Chemical Structure
Description
5-bromo-3-chloro-1H-indazole (CAS 36760-19-7) is a high-purity analytical reference standard with the molecular formula C7H12BrClN2 and a molecular weight of 239.54 g/mol.
Owing to a nitrile group, chlorine/bromine substitution, 5-bromo-3-chloro-1H-indazole is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 239.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 5-bromo-3-chloro-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.
