5-(3,5-Difluoro-4-methylphenyl)-1H-1,2,3-triazole (CAS 2306270-95-9), molecular formula C9H7F2N3 and molecular weight 195.17 g/mol, is a CATO reference standard with documented purity and traceability.
5-(3,5-Difluoro-4-methylphenyl)-1H-1,2,3-triazole (C9H7F2N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. Halogen substitution raises its density and boiling point; 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).
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.
