Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 122.07 g/mol gives 2,2-Difluorocyclopropanecarboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,2-Difluorocyclopropanecarboxylic acid (CAS 107873-03-0), a certified reference material (molecular formula C4H4F2O2, MW 122.07 g/mol) for analytical method development and quality control.
Structurally, 2,2-Difluorocyclopropanecarboxylic acid (C4H4F2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 122.07 g/mol, it falls into the low-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,2-Difluorocyclopropanecarboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
