Chemical Structure
Description
The occurrence of Bis(2-Chlorophenyl)sulfane is closely related to sulfur-containing functionality, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Bis(2-Chlorophenyl)sulfane (CAS 5097-95-0), molecular formula C12H8Cl2S and molecular weight 255.16 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, chlorine substitution, an aromatic ring system, Bis(2-Chlorophenyl)sulfane is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 255.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
