Rostabil TPP is an aryl phosphite in the form of a clear liquid with a characteristic, delicate fragrance. It is used as an intermediate in many chemical syntheses. Phosphorus on the third oxidation stage affects its good reduction capabilities used in the deoxygenation process, e.g. sulphoxides to sulfides or aliphatic epoxides to alkenes. The mildly nucleophilic nature of phosphite is used in the conversion of alcohols to alkyl halides.
