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.
Boiling point: 198 °C (388 °F; 471 K) Hazards GHS labelling: Pictograms. ... Thiophene-2-carboxaldehyde is an organosulfur compound with the formula C 4 H 3 SCHO.
Melting point: −10 °C (14 °F; 263 K) Boiling point: 153.5 °C (308.3 °F; 426.6 K) ... the 2-bromo isomer is prepared directly by partial bromination of thiophene.
Benzothiophene has no household use. In addition to benzo[b]thiophene, a second isomer is known: benzo[c]thiophene. [3] Benzothiophene finds use in research as a starting material for the synthesis of larger, usually bioactive structures.
