1,2-Bis(5-(trimethylstannyl)thiophen-2-yl)ethyne (CAS 1610057-24-3), molecular formula C16H22S2Sn2 and molecular weight 515.90 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,2-Bis(5-(trimethylstannyl)thiophen-2-yl)ethyne (C16H22S2Sn2) 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 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.
