3-(Chloromethyl)-5-(trifluoromethyl)-1,2,4-oxadiazole (CAS 890095-69-9) is a high-purity analytical reference standard with the molecular formula C4H2ClF3N2O and a molecular weight of 186.52 g/mol.
The molecular framework of 3-(Chloromethyl)-5-(trifluoromethyl)-1,2,4-oxadiazole (C4H2ClF3N2O) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
