Description

Compared with other compounds in its class, the molecular weight of 498.66 g/mol gives 1,4-Diethyl 2,5-dithieno[3,2-b]thien-2-yl-1,4-benzenedicarboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,4-Diethyl 2,5-dithieno[3,2-b]thien-2-yl-1,4-benzenedicarboxylate (CAS 1411976-67-4), molecular formula C24H18O4S4 and molecular weight 498.66 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,4-Diethyl 2,5-dithieno[3,2-b]thien-2-yl-1,4-benzenedicarboxylate (C24H18O4S4) 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 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.

CATO manufactures 1,4-Diethyl 2,5-dithieno[3,2-b]thien-2-yl-1,4-benzenedicarboxylate 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.
