2-Methyl-5-(4-trifluoromethoxy-phenyl)-furan-3-carboxylic acid amide (CAS 1858249-86-1), molecular formula C13H10F3NO3 and molecular weight 285.22 g/mol, is a CATO reference standard with documented purity and traceability.
2-Methyl-5-(4-trifluoromethoxy-phenyl)-furan-3-carboxylic acid amide (C13H10F3NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
