5-bromo-7-fluoro-1H-indazole CAS 1260381-83-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-bromo-7-fluoro-1H-indazole.

5-bromo-7-fluoro-1H-indazole (CAS 1260381-83-6), molecular formula C7H12BrFN2 and molecular weight 223.09 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H12BrFN2, 5-bromo-7-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.

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.
