Chemical Structure
Description
5-Bromo-1H-indazole-3-carbonitrile, 97% (CAS 201227-39-6), molecular formula C8H4BrN3 and molecular weight 222.04 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-Bromo-1H-indazole-3-carbonitrile, 97% (C8H4BrN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 222.04 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 5-Bromo-1H-indazole-3-carbonitrile, 97% 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.
