Chemical Structure
Description
As a certified reference material (CRM), 2,6-Bis(tributylstannyl)dithieno[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.
2,6-Bis(tributylstannyl)dithieno[3,2-b:2',3'-d]thiophene (CAS 944257-56-1) is a high-purity analytical reference standard with the molecular formula C32H56S3Sn2 and a molecular weight of 774.40 g/mol.
The molecular framework of 2,6-Bis(tributylstannyl)dithieno[3,2-b:2',3'-d]thiophene (C32H56S3Sn2) is characterized by sulfur-containing functionality, an aromatic ring 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
