Chemical Structure
Description
CATO supplies (4-Bromo-2-fluorobenzyl)(3-chlorophenyl)sulfane (CAS 1405940-53-5), a certified reference material (molecular formula C13H9BrClFS, MW 331.63 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, fluorine/chlorine/bromine substitution, an aromatic ring system, (4-Bromo-2-fluorobenzyl)(3-chlorophenyl)sulfane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 331.63 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.
