Cyclopropyl phenyl sulfide is a mixed alkyl–aryl thio-ether in which a cyclopropyl group is directly attached to sulfur. The compound is air- and photo-stable, freely miscible with common organic solvents (dichloromethane, ethyl acetate, toluene, alcohols) and essentially insoluble in water. Commercial material is supplied ≥98 % pure.
