Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
2-{[3-cyano-5-(thiophene-2-carbonyl)-6-(trifluoromethyl)pyridin-2-yl]sulfanyl}acetic acid (CAS 851879-11-3), molecular formula C14H7F3N2O3S2 and molecular weight 372.34 g/mol, is a CATO reference standard with documented purity and traceability.
2-{[3-cyano-5-(thiophene-2-carbonyl)-6-(trifluoromethyl)pyridin-2-yl]sulfanyl}acetic acid (C14H7F3N2O3S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. 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).
As a certified reference material (CRM), 2-{[3-cyano-5-(thiophene-2-carbonyl)-6-(trifluoromethyl)pyridin-2-yl]sulfanyl}acetic 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.
