3-Methylthiophene is an organosulfur compound with the formula CH 3 C 4 H 3 S. It is a colorless, flammable liquid. It can be produced by sulfidation of 2-methylsuccinate. [1] Like its isomer 2-methylthiophene, its commercial synthesis involvess vapor-phase dehydrogenation of suitable precursors.
The high reactivity of thiophene toward sulfonation is the basis for the separation of thiophene from benzene, which are difficult to separate by distillation due to their similar boiling points (4 °C difference at ambient pressure). Like benzene, thiophene forms an azeotrope with ethanol.

This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
2-Methylthiophene is an organosulfur compound with the formula CH 3 C 4 H 3 S. It is a colorless, flammable liquid. It can be produced by Wolff-Kishner reduction of thiophene-2-carboxaldehyde. [1] Its commercial synthesis involvess vapor-phase dehydrogenation of a 1-pentanol/CS 2 mixture. [2]

Thiophenol is an organosulfur compound with the formula C 6 H 5 SH, sometimes abbreviated as PhSH. This foul-smelling colorless liquid is the simplest aromatic thiol.The chemical structures of thiophenol and its derivatives are analogous to phenols, where the oxygen atom in the hydroxyl group (-OH) bonded to the aromatic ring in phenol is replaced by a sulfur atom.
