4-Bromo-2-(4-fluorophenyl)-6-methyl-2H-benzo[d][1,2,3]triazol-5-amine CAS 952948-67-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Bromo-2-(4-fluorophenyl)-6-methyl-2H-benzo[d][1,2,3]triazol-5-amine.

4-Bromo-2-(4-fluorophenyl)-6-methyl-2H-benzo[d][1,2,3]triazol-5-amine (CAS 952948-67-3) is a high-purity analytical reference standard with the molecular formula C13H10BrFN4 and a molecular weight of 321.15 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution, 4-Bromo-2-(4-fluorophenyl)-6-methyl-2H-benzo[d][1,2,3]triazol-5-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 321.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
