Chemical Structure

2,2-Difluoropentanedioic Acid CAS 380-86-9 chemical structure

Description

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.

CATO supplies 2,2-Difluoropentanedioic Acid (CAS 380-86-9), a certified reference material (molecular formula C5H6F2O4, MW 168.10 g/mol) for analytical method development and quality control.

2,2-Difluoropentanedioic Acid (C5H6F2O4) contains a carbohydrate-derived structure, fluorine substitution. It is notably hygroscopic, 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.

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.
