Ethyl hexanoate

Ethyl hexanoate ( CAS 123-66-0 ), also known by its FEMA 2439 designation and commercially as ethyl caproate, is a fruity ester used as a flavoring agent and fragrance ingredient across food, cosmetic, and industrial applications.

Its characteristic apple-pineapple odor profile makes it a target compound for flavor houses and fragrance formulators sourcing aroma chemicals at scale. In food and beverage manufacturing, it functions as a flavoring agent.

It is used in fruit-type confectionery, alcoholic beverages, and dairy products where tropical and apple notes are required. Fragrance formulators incorporate it into personal care products including lotions, shampoos, and body washes.

These applications deliver light, fresh top notes to the consumer. As a synthetic ester, it also sees use as a lubricant additive and plasticizer component in specialty industrial formulations where low-viscosity ester chemistry is specified.

Flavor blenders reference its regulatory status when qualifying it for use in regulated food applications in the US market. The compound is supplied as a clear liquid in drum and IBC quantities suited to industrial procurement.

It is available in food-grade and fragrance-grade specifications, with FCC grade material commonly requested for flavor applications. Purity levels of 98% and above are standard for flavor and fragrance end uses.
