3-Mercaptopropionic acid was originally mainly used as an intermediate for Chlormezanone.
In recent years, due to technological innovation, 3-mercaptopropionic acid has been newly applied. A new type of cement admixture, polycarboxylic acid water reducing agent, has been developed and used in large quantities. 3-mercaptopropionic acid is mainly used in the production of polymer The molecular weight control and high-performance mediator in carboxylic acid water reducer greatly improve the water reduction rate and slump retention of concrete. 3-mercaptopropionic acid is superior to other similar products in the polymerization of polycarboxylic acid superplasticizers.
