4,4'-((Thiocarbonylbis(sulfanediyl))bis(methylene))dibenzoic acid CAS 501950-24-9

Description

The occurrence of 4,4'-((Thiocarbonylbis(sulfanediyl))bis(methylene))dibenzoic acid is closely related to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4,4'-((Thiocarbonylbis(sulfanediyl))bis(methylene))dibenzoic acid (CAS 501950-24-9), molecular formula C17H14O4S3 and molecular weight 378.49 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4,4'-((Thiocarbonylbis(sulfanediyl))bis(methylene))dibenzoic acid (C17H14O4S3) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 378.49 g/mol, it falls into the moderately-high-molecular-weight range. 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), 4,4'-((Thiocarbonylbis(sulfanediyl))bis(methylene))dibenzoic 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.
