Chemical Structure

1-(2-Chloro-4-fluorophenyl)cyclopropane-1-carboxylic acid CAS 920501-50-4 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.

1-(2-Chloro-4-fluorophenyl)cyclopropane-1-carboxylic acid (CAS 920501-50-4), molecular formula C10H8ClFO2 and molecular weight 214.62 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H8ClFO2, 1-(2-Chloro-4-fluorophenyl)cyclopropane-1-carboxylic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 214.62 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
