p-Toluene sulfonamide was used to prepare the precursor required for synthesis of ethyl 6-phenyl-1-tosyl-1,2,5,6-tetrahydropyridine-3-carboxylate. It act as a derivative of ammonia activated to alkylation by alkyl halides is exemplified by the synthesis of N-tosyl-2,3-dihydroisoindole from o-xylylene dibromide. It is a precursor of N-tosyl imines.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
