6-Bromo-4-fluoro-3-iodo-1H-indazole CAS 887568-00-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Bromo-4-fluoro-3-iodo-1H-indazole.

6-Bromo-4-fluoro-3-iodo-1H-indazole (CAS 887568-00-5), molecular formula C7H3BrFIN2 and molecular weight 340.92 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6-Bromo-4-fluoro-3-iodo-1H-indazole (C7H3BrFIN2) is characterized by a nitrile group, fluorine/bromine/iodine substitution, an aromatic ring system. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
