Chemical Structure

Ethyl 4-chloro-3,3-difluorobutanoate CAS 2138411-53-5 chemical structure

Description

Ethyl 4-chloro-3,3-difluorobutanoate (C6H9ClF2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine 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.

CATO supplies Ethyl 4-chloro-3,3-difluorobutanoate (CAS 2138411-53-5), a certified reference material (molecular formula C6H9ClF2O2, MW 186.58 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.
