3-Mercaptopropionic acid (3-MPA) is an organosulfur compound with the formula HSCH2CH2CO2H.
It is a bifunctional molecule, containing both carboxylic acid and thiol groups. It is a colorless oil. It is derived from the addition of hydrogen sulfide to acrylic acid.
3-Mercaptopropionic Acid (MPA) is used in a variety of applications. The MPA itself is used as cocatalyst in the manufacture of Bisphenol A, which is a key raw material in Polycarbonate production. MPA enhances the process efficiency.
Another application is as Chain Transfer Agent (CTA) during Polymerisation of Polycarboxylates which are used in the building industry as superplasticiser in concrete.
