Chemical Structure
Description
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.
2-{[4-(ethanesulfonyl)phenyl]sulfanyl}benzoic acid (CAS 1154352-92-7), molecular formula C15H14O4S2 and molecular weight 322.40 g/mol, is a CATO reference standard with documented purity and traceability.
2-{[4-(ethanesulfonyl)phenyl]sulfanyl}benzoic acid (C15H14O4S2) contains a flavonoid core, a sulfone 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.
As a certified reference material (CRM), 2-{[4-(ethanesulfonyl)phenyl]sulfanyl}benzoic 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.
