Chemical Structure

7-Bromo-5-fluoro-2-methyl-2H-indazole CAS 2090433-95-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Bromo-5-fluoro-2-methyl-2H-indazole.

7-Bromo-5-fluoro-2-methyl-2H-indazole (CAS 2090433-95-5), molecular formula C8H6BrFN2 and molecular weight 229.05 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 7-Bromo-5-fluoro-2-methyl-2H-indazole (C8H6BrFN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 229.05 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 7-Bromo-5-fluoro-2-methyl-2H-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.
