Pyridine p-toluenesulfonate,also known as 4-methylbenzenesulfonate,PPT,is a white crystalline and powder with the molecular formula C7H8O3S·C5H5N.

It is highly hygroscopic and needs to be stored in a closed container.It should be stored in a cool,dry,and well ventilated place,away from incompatible substances.

In organic synthesis,pyridinium p-toluenesulfonate is a widely used,mild,and laboratory prepared acidic catalyst.It can be simply regarded as a substitute for p-toluenesulfonic acid,and all reactions completed by p-toluenesulfonic acid can also be completed.

However,it has more advantages in use than toluene sulfuric acid.

For example,p-toluenesulfonic acid generally exists and is used in the form of monohydrate crystals,while p-toluenesulfonic acid pyridine salt is anhydrous;P-toluenesulfonic acid has strong acidity,while the acidity of p-toluenesulfonic acid pyridine salt does not have a significant impact on many acid sensitive functional groups.

Therefore,pyridine p-toluenesulfonate has a wider application prospect.Nanjing Shunxiang seized this opportunity and further optimized the production process and raw materials of pyridine p-toluenesulfonate with its modern technology,so that it can serve customers with excellent product quality,high-quality service,and competitive prices.
