Chemical Structure

2,2-Difluoro-4-pentenoic Acid CAS 55039-89-9 chemical structure

Description

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.

2,2-Difluoro-4-pentenoic Acid (CAS 55039-89-9), molecular formula C5H6F2O2 and molecular weight 136.10 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2,2-Difluoro-4-pentenoic Acid (C5H6F2O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.

CATO manufactures 2,2-Difluoro-4-pentenoic Acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
