2,6-Diiodo-dithieno[3,2-b;2',3'-d]thiophene CAS 1028527-04-9

Description

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.

2,6-Diiodo-dithieno[3,2-b;2',3'-d]thiophene (CAS 1028527-04-9) is a high-purity analytical reference standard with the molecular formula C8H2I2S3 and a molecular weight of 448.11 g/mol.

Owing to sulfur-containing functionality, iodine substitution, an aromatic ring system, 2,6-Diiodo-dithieno[3,2-b;2',3'-d]thiophene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 448.11 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).

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.
