Chemical Structure
Description
The occurrence of (4-Fluorobenzyl)(phenyl)sulfane is closely related to sulfur-containing functionality, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(4-Fluorobenzyl)(phenyl)sulfane (CAS 351-66-6), molecular formula C13H11FS and molecular weight 218.29 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, fluorine substitution, an aromatic ring system, (4-Fluorobenzyl)(phenyl)sulfane is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 218.29 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.
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.
