Thiocarbanilide is an organic chemical compound with the formula (C₆H₅NH)₂CS. This white solid is a derivative of thiourea. It is prepared by the reaction of aniline and carbon disulfide.

Uses

Thiocarbanilide is commonly used as a vulcanization accelerator for rubber,^[2] and as a stabilizer for PVC and PVDC. Its use as a vulcanization accelerator was discovered by BF Goodrich chemist George Oenslager.^[3]

Reactions

Thiocarbanilide reacts with phosphorus pentachloride or hydrochloric acid, dilute sulfuric acid, acetic anhydride or iodine to produce phenyl isothiocyanate.{{Citation needed|date=March 2011}}
