Compared with other compounds in its class, the molecular weight of 270.73 g/mol gives (3-Chloro-4-fluorobenzyl)(4-fluorophenyl)sulfane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (3-Chloro-4-fluorobenzyl)(4-fluorophenyl)sulfane (CAS 1443340-65-5), a certified reference material (molecular formula C13H9ClF2S, MW 270.73 g/mol) for analytical method development and quality control.
(3-Chloro-4-fluorobenzyl)(4-fluorophenyl)sulfane (C13H9ClF2S) contains sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
