Chemical Structure
Description
The occurrence of 2-(3,5-Dichlorophenyl)ethane-1-thiol 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.
CATO supplies 2-(3,5-Dichlorophenyl)ethane-1-thiol (CAS 1174005-49-2), a certified reference material (molecular formula C8H8Cl2S, MW 207.12 g/mol) for analytical method development and quality control.
Based on its molecular formula C8H8Cl2S, 2-(3,5-Dichlorophenyl)ethane-1-thiol contains sulfur-containing functionality, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 207.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
