Chemical Structure
Description
3-((2-Chlorophenyl)thio)benzoicacid (CAS 141358-05-6), molecular formula C13H9ClO2S and molecular weight 264.73 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C13H9ClO2S, 3-((2-Chlorophenyl)thio)benzoicacid contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 264.73 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.
As a certified reference material (CRM), 3-((2-Chlorophenyl)thio)benzoicacid 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.
