Description
CATO manufactures 3-(2-Trifluoromethyl-phenyl)-thiophene 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.
3-(2-Trifluoromethyl-phenyl)-thiophene (CAS 876319-71-0) is a high-purity analytical reference standard with the molecular formula C11H7F3S and a molecular weight of 228.23 g/mol.
Owing to sulfur-containing functionality, fluorine substitution, an aromatic ring system, 3-(2-Trifluoromethyl-phenyl)-thiophene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 228.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
