What is 3-Mercaptopropionic acid?

     With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is 3-Mercaptopropionic acid which has developed particularly rapidly in recent years. Do you know about 3-Mercaptopropionic acid?

The official answer: Mercaptopropionic acid is an organic substance with the chemical formula C3H6O2S. It is a transparent liquid with a strong sulphide odour and is foul-smelling and toxic. It is used as an intermediate for the pharmaceutical fenaral and as a stabilizer for polyvinyl chloride.It is made from acrylonitrile and thiourea as raw material. Firstly, thiourea and hydrochloric acid are reacted at 40℃ for 0.5h, acrylonitrile is added dropwise, reacted at 110-113℃ for 3h, cooled to 40℃, 4% sodium hydroxide solution is added to pH 11, dehydrogenated for 4h, then neutralised at 3Chemicalbook0℃ with hydrochloric acid to pH 1-2. Then benzene is added to extract, benzene is recovered and distilled under reduced pressure, 125-140℃ fraction is collected to obtain finished product. In addition, 3-mercaptopropionic acid can also be produced by the reaction of hydrogen sulphide with pyruvic acid or with β-propanolactone.

What’s the application of 3-Mercaptopropionic acid?

It is used as an intermediate for the pharmaceutical fenaryl and as a stabilizer for polyvinyl chloride. Like thioglycolic acid, it can be used in transparent products and has a very good thermal stability, superior to other stabilisers. It is also used as an antioxidant, catalyst and biochemical reagent. Used as an antioxidant, catalyst and biochemical reagent. High speed RP-HPLC/FC analysis of amino acids.
