Chemical Structure
Description
The occurrence of 1-(2,4-Difluorophenyl)cyclopropanecarboxylic Acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-(2,4-Difluorophenyl)cyclopropanecarboxylic Acid (CAS 920501-68-4), a certified reference material (molecular formula C10H8F2O2, MW 198.17 g/mol) for analytical method development and quality control.
Structurally, 1-(2,4-Difluorophenyl)cyclopropanecarboxylic Acid (C10H8F2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 198.17 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
