Docosanedioic acid is primarily utilized in the production of high-performance polymers and specialty coatings. Its long hydrocarbon chain contributes to the enhancement of flexibility, durability, and chemical resistance in materials such as polyamides and polyesters. This makes it valuable in applications requiring robust performance under harsh conditions, such as automotive parts, industrial coatings, and protective films. Additionally, it serves as a key intermediate in the synthesis of lubricants and surfactants, where its properties help reduce friction and improve stability. In the cosmetic industry, it is used in the formulation of emollients and skin-conditioning agents, providing smoothness and moisture retention in skincare products. Its versatility also extends to biomedical applications, where it is explored for use in drug delivery systems and biodegradable materials.
