2,3':4',2''-Terthiophene CAS 101306-11-0 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

2,3':4',2''-Terthiophene (CAS 101306-11-0) is a high-purity analytical reference standard with the molecular formula C12H8S3 and a molecular weight of 248.39 g/mol.

Owing to sulfur-containing functionality, an aromatic ring system, 2,3':4',2''-Terthiophene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 248.39 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).

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.
