Chemical Structure
Description
The occurrence of 5-((Trifluoromethyl)thio)furan-2-carboxylic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-((Trifluoromethyl)thio)furan-2-carboxylic acid (CAS 1340136-76-6) is a high-purity analytical reference standard with the molecular formula C6H3F3O3S and a molecular weight of 212.15 g/mol.
5-((Trifluoromethyl)thio)furan-2-carboxylic acid (C6H3F3O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 5-((Trifluoromethyl)thio)furan-2-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
