Chemical Structure
Description
The molecular framework of 7-Bromo-5-fluoro-1H-indazole (C7H12BrFN2) is characterized by 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies 7-Bromo-5-fluoro-1H-indazole (CAS 1100214-35-4), a certified reference material (molecular formula C7H12BrFN2, MW 223.09 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
