Additionally, it is utilized in the production of perfumes and fragrances due to its pleasant odor. In industrial applications, it acts as a solvent for resins, coatings, and adhesives, contributing to the formulation of high-performance materials. Its stability and reactivity also make it valuable in organic synthesis and chemical research.
