4-Dimethylamino-4-ethoxy-1,1,1-trifluoro-but-3-en-2-one CAS 128648-62-4

Description

The occurrence of 4-Dimethylamino-4-ethoxy-1,1,1-trifluoro-but-3-en-2-one is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Dimethylamino-4-ethoxy-1,1,1-trifluoro-but-3-en-2-one (CAS 128648-62-4), a certified reference material (molecular formula C8H12F3NO2, MW 211.18 g/mol) for analytical method development and quality control.

The molecular framework of 4-Dimethylamino-4-ethoxy-1,1,1-trifluoro-but-3-en-2-one (C8H12F3NO2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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.

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.
