Diethyl dithieno[3,2-b:2',3'-d]thiophene-2,6-dicarboxylate CAS 502764-52-5

Description

Diethyl dithieno[3,2-b:2',3'-d]thiophene-2,6-dicarboxylate (C14H12O4S3) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. It is notably hygroscopic, 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 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).

Diethyl dithieno[3,2-b:2',3'-d]thiophene-2,6-dicarboxylate (CAS 502764-52-5) is a high-purity analytical reference standard with the molecular formula C14H12O4S3 and a molecular weight of 340.44 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.

As a certified reference material (CRM), Diethyl dithieno[3,2-b:2',3'-d]thiophene-2,6-dicarboxylate 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.
