Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 223.23 g/mol gives 2-(2-Cyanophenyl)benzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(2-Cyanophenyl)benzoic acid (CAS 57743-13-2) is a high-purity analytical reference standard with the molecular formula C14H9NO2 and a molecular weight of 223.23 g/mol.
2-(2-Cyanophenyl)benzoic acid (C14H9NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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 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.
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.
