Chemical Structure
Description
3-(4-Methoxyphenyl)thiophene (CAS 82437-75-0) is a high-purity analytical reference standard with the molecular formula C11H10OS and a molecular weight of 190.26 g/mol.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 3-(4-Methoxyphenyl)thiophene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 190.26 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.
