Chemical Structure
Description
rel-(1R,2R)-2-fluoro-2-phenylcyclopropane-1-carboxylic acid (C10H9FO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
rel-(1R,2R)-2-fluoro-2-phenylcyclopropane-1-carboxylic acid (CAS 309242-45-3) is a high-purity analytical reference standard with the molecular formula C10H9FO2 and a molecular weight of 180.18 g/mol.
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.
