1-Chloro-1,1-difluoropentane-2,4-dione CAS 2375-76-0

Description

The occurrence of 1-Chloro-1,1-difluoropentane-2,4-dione is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-Chloro-1,1-difluoropentane-2,4-dione (CAS 2375-76-0), a certified reference material (molecular formula C5H5ClF2O2, MW 170.54 g/mol) for analytical method development and quality control.

Based on its molecular formula C5H5ClF2O2, 1-Chloro-1,1-difluoropentane-2,4-dione contains a carboxylic acid group, 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 170.54 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.
