The title compound, C13H17N3S, was synthesized by the reaction of 4-pentylbenzoic acid and thiosemicarbazide. The dihedral angle between the thiadiazole and phenyl rings is 29.9 (2)°. An intramolecular C-HS interaction is observed. In the crystal, intermolecular N-HN hydrogen bonding links the molecules into centrosymmetric dimers.
