Chemical Structure
Description
The occurrence of 2-Methylthiophene-3-carbonitrile is closely related to a nitrile group, sulfur-containing functionality, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Methylthiophene-3-carbonitrile (CAS 53562-50-8), a certified reference material (molecular formula C6H5NS, MW 123.18 g/mol) for analytical method development and quality control.
Owing to a nitrile group, sulfur-containing functionality, an aromatic ring system, 2-Methylthiophene-3-carbonitrile is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 123.18 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).
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.
