Chemical Structure
Description
The molecular framework of 3,3'-(Disulfanediylbis(3,1-phenylene))dipropanoic acid (C18H18O4S2) is characterized by a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
3,3'-(Disulfanediylbis(3,1-phenylene))dipropanoic acid (CAS 63684-32-2) is a high-purity analytical reference standard with the molecular formula C18H18O4S2 and a molecular weight of 362.46 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.
CATO manufactures 3,3'-(Disulfanediylbis(3,1-phenylene))dipropanoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
