7,7'-Bis(tributylstannyl)-2,2',3,3'-tetrahydro-5,5'-bithieno[3,4-b][1,4]dioxine (CAS 250726-95-5) is a high-purity analytical reference standard with the molecular formula C36H62O4S2Sn2 and a molecular weight of 860.43 g/mol.
The molecular framework of 7,7'-Bis(tributylstannyl)-2,2',3,3'-tetrahydro-5,5'-bithieno[3,4-b][1,4]dioxine (C36H62O4S2Sn2) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
