Chemical Industry: Used in the production of surfactants (e.g., sodium decanoate, decyl betaine), detergents, plasticizers, lubricant additives, etc.; also used as intermediates in organic synthesis for the preparation of fragrances, dyes, etc.

Pharmaceutical Field: Its derivatives (e.g., nandrolone decanoate) can be used as raw materials for hormone drugs; some decanoate esters possess antibacterial activity and are used in the preparation of topical disinfectants.

Others: Used in cosmetics (e.g., creams, shampoos) to adjust oil texture, or as release agents in plastic processing.
