Monoethyl itaconate is widely used in the polymer industry as a monomer for producing specialty polymers and resins. It is particularly valued for its ability to enhance the flexibility and durability of polymer coatings, making it suitable for applications in paints, adhesives, and sealants. Additionally, it serves as a key intermediate in the synthesis of bio-based plastics, contributing to the development of sustainable materials. In the medical field, it has shown potential in drug delivery systems due to its biocompatibility and ability to form stable polymeric matrices. Its use in the production of biodegradable plastics also aligns with efforts to reduce environmental impact.
