N'-(3-bromo-4-fluorobenzylidene)-4-methylbenzenesulfonohydrazide CAS 2131827-25-1

Description

N'-(3-bromo-4-fluorobenzylidene)-4-methylbenzenesulfonohydrazide (CAS 2131827-25-1) is a high-purity analytical reference standard with the molecular formula C14H12BrFN2O2S and a molecular weight of 371.22 g/mol.

Based on its molecular formula C14H12BrFN2O2S, N'-(3-bromo-4-fluorobenzylidene)-4-methylbenzenesulfonohydrazide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 371.22 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.
