Chemical Structure
Description
Owing to sulfur-containing functionality, a polycyclic aromatic system, 5,5''-Bis(trimethylstannyl)-2,2':5',2''-terthiophene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 574.00 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
5,5''-Bis(trimethylstannyl)-2,2':5',2''-terthiophene (CAS 178931-63-0), molecular formula C18H24S3Sn2 and molecular weight 574.00 g/mol, is a CATO reference standard with documented purity and traceability.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
