4,4,4-trifluoro-2-butynoic acid ethyl ester 79424-03-6 A839682 ethyl 4,4,4-tris(fluoranyl)but-2-ynoate (CAS 79424-03-6), molecular formula C6H5F3O2 and molecular weight 166.10 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4,4,4-trifluoro-2-butynoic acid ethyl ester 79424-03-6 A839682 ethyl 4,4,4-tris(fluoranyl)but-2-ynoate (C6H5F3O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.
