Chemical Structure

5,5'-Diiodo-2,2'-bithiophene CAS 3339-80-8 chemical structure

Description

Based on its molecular formula C8H4I2S2, 5,5'-Diiodo-2,2'-bithiophene contains sulfur-containing functionality, iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 418.06 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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'-Diiodo-2,2'-bithiophene (CAS 3339-80-8) is a high-purity analytical reference standard with the molecular formula C8H4I2S2 and a molecular weight of 418.06 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.
