3-Decanol is widely used in the fragrance and flavor industry due to its pleasant, citrus-like aroma. It serves as a key ingredient in the formulation of perfumes, colognes, and scented personal care products, adding a fresh and slightly floral note.

In the food industry, it is utilized as a flavoring agent to enhance the taste of various products, particularly those requiring a citrus or fruity profile.

Additionally, it is employed in the production of synthetic lubricants and plasticizers, where it acts as an intermediate chemical. Its properties also make it useful in the synthesis of other organic compounds for industrial applications.
