Chemical Structure

3-methoxythiophene CAS 17573-92-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 118.20 g/mol gives 3-methoxythiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3-methoxythiophene (CAS 17573-92-1), a certified reference material (molecular formula C5H10OS, MW 118.20 g/mol) for analytical method development and quality control.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, 3-methoxythiophene is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 118.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
