Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 3-(Benzo[b]thiophen-3-yl)propanenitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 187.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
3-(Benzo[b]thiophen-3-yl)propanenitrile (CAS 843652-83-5) is a high-purity analytical reference standard with the molecular formula C11H9NS and a molecular weight of 187.26 g/mol.
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.
