Chemical Structure
Description
The occurrence of 2-(difluoromethyl)cyclopropanecarboxylic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-(difluoromethyl)cyclopropanecarboxylic acid (CAS 1314960-20-7), a certified reference material (molecular formula C5H6F2O2, MW 136.10 g/mol) for analytical method development and quality control.
Based on its molecular formula C5H6F2O2, 2-(difluoromethyl)cyclopropanecarboxylic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 136.10 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.
CATO manufactures 2-(difluoromethyl)cyclopropanecarboxylic 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.
