Chemical Structure
Description
2,2'-(Ethane-1,2-diylbis(sulfanediyl))dibenzoic acid (C16H14O4S2) 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).
2,2'-(Ethane-1,2-diylbis(sulfanediyl))dibenzoic acid (CAS 52961-83-8) is a high-purity analytical reference standard with the molecular formula C16H14O4S2 and a molecular weight of 334.41 g/mol.
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.
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.
