1-Chloro-3,3,3-trifluoroacetone CAS 431-37-8 chemical structure

Description

CATO supplies 1-Chloro-3,3,3-trifluoroacetone (CAS 431-37-8), a certified reference material (molecular formula C3H2ClF3O, MW 146.50 g/mol) for analytical method development and quality control.

Based on its molecular formula C3H2ClF3O, 1-Chloro-3,3,3-trifluoroacetone contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 146.50 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.

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.
