The term of tosyl is for p-toluene sulfonic acid ester functional group, the conjugate base of the strong acid, p-toluenesulfonic acid. The tosyl group, like other sulfonates, has electron-withdrawing properties. It is a highly reactive leaving group due to the stability of resonance structure.
Application of p-toluene sulphonic acid Pere-toluene sulfonic acid is a strong organic acid, the acid stronger than benzoic acid millions of times.This acid is unique in that it is usually the case for a solid, convenient. Another advantage is that compared with snorganic acid not oxidizing, can in some cases replace the inorganic acid. 1.Catalyst.
Hydrazide is an acyl hydrazine. Acyl (-CO) is an organic radical formed by removal of a hydroxyl group from an organic acid (carboxyl group). p-Toluenesulfonyl Hydrazide is a foaming agent for rubbers and plastics such as PVC, EVA, polyolefin, polystyrene products.
Application p-Toluenesulfonyl hydrazide was used as a reagent for the preparation of tosylhydrazones. It was used to prepare dipyrazolo[1,5-a:4′,3′-c] pyridines and 1,2,3-selenadiazole derivatives.

Hydrazides in organic chemistry are a class of organic compounds sharing a common functional group characterized by hydrazine core in which at least one of the hydrogen atoms is replaced by a substituent that is an acyl group. The general structure for a hydrazide is E(=O)-NR-NR 2, where the R's are frequently hydrogens.
