Chemical Structure

(5,5'-(2,5-Bis((2-butyloctyl)oxy)-1,4-phenylene)bis(thieno[3,2-b]thiophene-5,2-diyl))bis(trimethylstannane) CAS 1914976-72-9 chemical structure

Description

The molecular framework of (5,5'-(2,5-Bis((2-butyloctyl)oxy)-1,4-phenylene)bis(thieno[3,2-b]thiophene-5,2-diyl))bis(trimethylstannane) (C48H74O2S4Sn2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

(5,5'-(2,5-Bis((2-butyloctyl)oxy)-1,4-phenylene)bis(thieno[3,2-b]thiophene-5,2-diyl))bis(trimethylstannane) (CAS 1914976-72-9) is a high-purity analytical reference standard with the molecular formula C48H74O2S4Sn2 and a molecular weight of 1048.78 g/mol.

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), (5,5'-(2,5-Bis((2-butyloctyl)oxy)-1,4-phenylene)bis(thieno[3,2-b]thiophene-5,2-diyl))bis(trimethylstannane) 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.
