Chemical Structure
Description
The occurrence of 5-(Trifluoromethyl)thiophene-2-carbonyl chloride is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-(Trifluoromethyl)thiophene-2-carbonyl chloride (CAS 679807-08-0), a certified reference material (molecular formula C6H2ClF3OS, MW 214.59 g/mol) for analytical method development and quality control.
5-(Trifluoromethyl)thiophene-2-carbonyl chloride (C6H2ClF3OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5-(Trifluoromethyl)thiophene-2-carbonyl chloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
