[4,4-Bis(2-ethylhexyl)-4H-cyclopenta[1,2-b:5,4-b’]dithiophene-2,6-diyl]bis(trimethylstannane) (CAS 920504-00-3) is a high-purity analytical reference standard with the molecular formula C31H54S2Sn2 and a molecular weight of 728.31 g/mol.
The molecular framework of [4,4-Bis(2-ethylhexyl)-4H-cyclopenta[1,2-b:5,4-b’]dithiophene-2,6-diyl]bis(trimethylstannane) (C31H54S2Sn2) 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 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.
