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.
4,4'-Sulfonylbis(2,6-dimethylphenol) (CAS 13288-70-5), molecular formula C16H18O4S and molecular weight 306.38 g/mol, is a CATO reference standard with documented purity and traceability.
4,4'-Sulfonylbis(2,6-dimethylphenol) (C16H18O4S) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 4,4'-Sulfonylbis(2,6-dimethylphenol) 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.
