Description
CATO supplies 2-(4-Fluorophenyl)sulfanylbenzoic acid (CAS 13420-72-9), a certified reference material (molecular formula C13H9FO2S, MW 248.27 g/mol) for analytical method development and quality control.
Based on its molecular formula C13H9FO2S, 2-(4-Fluorophenyl)sulfanylbenzoic acid contains a sulfone group, 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 248.27 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(4-Fluorophenyl)sulfanylbenzoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
