Chemical Structure

Benzo[b]thiophene-7-carbonitrile CAS 22780-71-8 chemical structure

Description

As a certified reference material (CRM), Benzo[b]thiophene-7-carbonitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

Benzo[b]thiophene-7-carbonitrile (CAS 22780-71-8) is a high-purity analytical reference standard with the molecular formula C9H5NS and a molecular weight of 159.21 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, Benzo[b]thiophene-7-carbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 159.21 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.
