Chemical Structure

(3R,3aS,6R,6aS)-hexahydrofuro[3,2-b]furan-3,6-diyl bis(4-methylbenzenesulfonate) CAS 67890-26-0 chemical structure

Description

The occurrence of (3R,3aS,6R,6aS)-hexahydrofuro[3,2-b]furan-3,6-diyl bis(4-methylbenzenesulfonate) 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.

(3R,3aS,6R,6aS)-hexahydrofuro[3,2-b]furan-3,6-diyl bis(4-methylbenzenesulfonate) (CAS 67890-26-0) is a high-purity analytical reference standard with the molecular formula C20H22O8S2 and a molecular weight of 454.51 g/mol.

The molecular framework of (3R,3aS,6R,6aS)-hexahydrofuro[3,2-b]furan-3,6-diyl bis(4-methylbenzenesulfonate) (C20H22O8S2) 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 the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
