2,7-Diethylbenzo[b]thiophene CAS 16587-45-4 chemical structure

Description

CATO supplies 2,7-Diethylbenzo[b]thiophene (CAS 16587-45-4), a certified reference material (molecular formula C12H14S, MW 190.30 g/mol) for analytical method development and quality control.

Owing to sulfur-containing functionality, an aromatic ring system, 2,7-Diethylbenzo[b]thiophene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 190.30 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).

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

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.
