Descrizione

Application

Thiophene may be used as an analytical reference standard for the quantification of the analyte in diesel oil[1] and crude oil[2] using two-dimensional gas chromatography with sulfur chemiluminescence detection.

General description

Thiophene belongs to the class of polycyclic aromatic sulfur heterocycles, which are carcinogenic compounds found in crude oil.[2] Thiopenes are widely used as building blocks in many agrochemicals, pharmaceuticals, and material science.[3]
