Chemical Structure
Description
The occurrence of 2,6-Diphenyldithieno[3,2-b:2’,3’-d]thiophene is closely related to sulfur-containing functionality, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,6-Diphenyldithieno[3,2-b:2’,3’-d]thiophene (CAS 881838-94-4), molecular formula C20H12S3 and molecular weight 348.50 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,6-Diphenyldithieno[3,2-b:2’,3’-d]thiophene (C20H12S3) is characterized by sulfur-containing functionality, a polycyclic aromatic system. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2,6-Diphenyldithieno[3,2-b:2’,3’-d]thiophene 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.
