Chemical Structure

5,5′-Bis(tributylstannyl)-2,2′-bithiophene CAS 171290-94-1 chemical structure

Description

Owing to sulfur-containing functionality, an aromatic ring system, 5,5′-Bis(tributylstannyl)-2,2′-bithiophene is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 744.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

5,5′-Bis(tributylstannyl)-2,2′-bithiophene (CAS 171290-94-1) is a high-purity analytical reference standard with the molecular formula C32H58S2Sn2 and a molecular weight of 744.35 g/mol.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
