Chemical Structure
Description
(E)-4-Ethoxy-4-propylamino-1,1,1-trifluorobut-3-en-2-one (CAS 1365994-94-0) is a high-purity analytical reference standard with the molecular formula C9H14F3NO2 and a molecular weight of 225.21 g/mol.
(E)-4-Ethoxy-4-propylamino-1,1,1-trifluorobut-3-en-2-one (C9H14F3NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
