Chemical Structure
Description
The occurrence of 4-Bromo-3-chloro-6-fluoro-1H-indazole is closely related to a nitrile group, fluorine/chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Bromo-3-chloro-6-fluoro-1H-indazole (CAS 887567-84-2), molecular formula C7H3BrClFN2 and molecular weight 249.47 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, fluorine/chlorine/bromine substitution, an aromatic ring system, 4-Bromo-3-chloro-6-fluoro-1H-indazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 249.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 4-Bromo-3-chloro-6-fluoro-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.
