Description

(Z)-3-[[3-(Octadec-9-Enyloxy)-3-Oxopropyl]Thio]Propionic Acid CAS NO 83438-56-6 is a specialized organosulfur compound featuring a long-chain oleyl ester group linked to a thiodipropionic acid core. This unique structure makes it a valuable intermediate and functional additive, particularly as a light stabilizer and antioxidant precursor in polymer systems. It is primarily utilized by manufacturers in the plastics, coatings, and specialty chemical industries seeking to enhance material longevity and performance under oxidative stress.

Application

• Polymer Stabilizer: Acts as a key intermediate in the synthesis of high-performance light stabilizers and antioxidants for polyolefins (PP, PE), PVC, and engineering plastics.
• Lubricant & Fuel Additive: Serves as a multifunctional additive in synthetic lubricants and industrial fuels, providing antioxidant and anti-wear properties.
• Coating Formulations: Incorporated into UV-curable coatings and paints to improve weatherability and prevent yellowing and degradation.
• Rubber Industry: Used as a non-staining antioxidant and antiozonant in the production of synthetic rubbers and elastomers.
• Specialty Surfactants: Functions as a building block for synthesizing specialized surfactants and emulsifiers with unique solubility profiles.
• Cosmetic & Personal Care: Employed as a stabilizer in formulations requiring protection against oxidation, such as in certain creams and lotions.
• Adhesives & Sealants: Enhances the thermal and oxidative stability of hot-melt and reactive adhesive systems.
