Principal Use
3-Mercaptopropionic acid and its derivatives are main materials for the synthesis of PVC-stabilizers and are used as chain transfer and cross-linking agents in polymerizations. These compounds are also useful as ion exchange catalysts, coupling agents, and in UV-curable formulations. 3-Mercaptopropionic acid is a clear, near water-white liquid with strong odor used as a basic material in the production of PVC stabilizers. 3,3′-Thiodiproprionic acid and its derivatives are used as a primary or secondary antioxidant and color stabilizer in combination with phenolic antioxidant for polymers including polyolefins, styrenics, rubbers, polyesters and soap industry. They are also used as an intermediate for the synthesis of organic compounds. They are approved to use in food packaging. They can be used as stabilizers in oils, lubricants, sealants, and adhesives. They are active ingredients of biocides can be used in personal care products
