Chemical Structure

2-(2-Ethylhexyl)thiophene CAS 4891-44-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 196.35 g/mol gives 2-(2-Ethylhexyl)thiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(2-Ethylhexyl)thiophene (CAS 4891-44-5), molecular formula C12H20S and molecular weight 196.35 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to sulfur-containing functionality, 2-(2-Ethylhexyl)thiophene is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 196.35 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.

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.
