Methyl nonanoate is widely used as a flavoring agent in the food industry due to its fruity and floral aroma, often incorporated into products like candies, baked goods, and beverages to enhance their sensory appeal. In the fragrance industry, it serves as a key ingredient in perfumes and cosmetics, providing a pleasant scent profile. Additionally, it is utilized in the synthesis of other chemicals, acting as an intermediate in the production of esters and other organic compounds. In agriculture, methyl nonanoate has been explored as a potential bio-pesticide, particularly as an insect attractant for pest control, offering an eco-friendly alternative to traditional chemical pesticides. Its applications also extend to research, where it is used as a reference compound in analytical chemistry and studies involving esterification processes.
