(E)-1-(3,4-Difluorophenyl)-5-(dimethylamino)-4-methyl-pent-1-en-3-one CAS 119644-57-4

Description

Based on its molecular formula C14H17F2NO, (E)-1-(3,4-Difluorophenyl)-5-(dimethylamino)-4-methyl-pent-1-en-3-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 253.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO supplies (E)-1-(3,4-Difluorophenyl)-5-(dimethylamino)-4-methyl-pent-1-en-3-one (CAS 119644-57-4), a certified reference material (molecular formula C14H17F2NO, MW 253.29 g/mol) for analytical method development and quality control.

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.
