Chemical Structure

7-bromo-4-fluoro-1H-indazole CAS 1000341-72-9 chemical structure

Description

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.

7-bromo-4-fluoro-1H-indazole (CAS 1000341-72-9) is a high-purity analytical reference standard with the molecular formula C7H12BrFN2 and a molecular weight of 223.09 g/mol.

Based on its molecular formula C7H12BrFN2, 7-bromo-4-fluoro-1H-indazole contains a nitrile group, fluorine/bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 223.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
