Chemical Structure
Description
The occurrence of (4-Chloro-2-fluorophenyl)(methyl)sulfane is closely related to sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(4-Chloro-2-fluorophenyl)(methyl)sulfane (CAS 1881328-30-8), molecular formula C7H6ClFS and molecular weight 176.64 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring system, (4-Chloro-2-fluorophenyl)(methyl)sulfane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 176.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
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.
