Chemical Structure
Description
Based on its molecular formula C11H11FO2, 2-(4-Fluorophenyl)cyclobutane-1-carboxylic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 194.20 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.
2-(4-Fluorophenyl)cyclobutane-1-carboxylic acid (CAS 1499764-95-2), molecular formula C11H11FO2 and molecular weight 194.20 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
