5-Bromo-7-fluoro-2-methyl-2H-indazole CAS 2004705-97-7

Description

The occurrence of 5-Bromo-7-fluoro-2-methyl-2H-indazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Bromo-7-fluoro-2-methyl-2H-indazole (CAS 2004705-97-7), molecular formula C8H6BrFN2 and molecular weight 229.05 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Bromo-7-fluoro-2-methyl-2H-indazole (C8H6BrFN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), 5-Bromo-7-fluoro-2-methyl-2H-indazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
