1,5-Hexanediol is widely used as a versatile intermediate in the production of polymers, particularly polyesters and polyurethanes. Its diol structure allows it to act as a building block, contributing to the flexibility and durability of the final materials. In coatings and adhesives, it enhances performance by improving adhesion and resistance to environmental factors. It also serves as a key component in the synthesis of plasticizers, which are added to plastics to increase their pliability. Additionally, 1,5-Hexanediol finds application in the manufacture of personal care products, such as moisturizers and lotions, where it acts as a humectant to retain moisture. Its role in the production of high-performance fibers and resins further highlights its importance in industrial applications.
