2,5-Hexanediol is widely used in the production of polymers and resins, particularly in the synthesis of polyesters and polyurethanes. Its diol functionality allows it to act as a building block, enhancing the flexibility and durability of the resulting materials. This makes it valuable in the manufacturing of coatings, adhesives, and elastomers. Additionally, it serves as a solvent in various industrial applications, including the formulation of inks, paints, and cleaning agents. In the personal care industry, it is utilized as a humectant and viscosity modifier in cosmetic products, helping to retain moisture and improve texture. Its applications also extend to the pharmaceutical sector, where it is used as an intermediate in the synthesis of active pharmaceutical ingredients (APIs).
