Chemical Structure
Description
The occurrence of 2-(5-Chlorothiophen-2-yl)ethane-1-thiol is closely related to sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-(5-Chlorothiophen-2-yl)ethane-1-thiol (CAS 1267057-16-8), a certified reference material (molecular formula C6H7ClS2, MW 178.70 g/mol) for analytical method development and quality control.
The molecular framework of 2-(5-Chlorothiophen-2-yl)ethane-1-thiol (C6H7ClS2) is characterized by sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
