Products Description of Gamma-Nonanolactone CAS# 104-61-0
Gamma-Nonalactone, also known as 5-pentyloxolan-2-one, is a clear oily liquid with an appearance ranging from colorless to pale yellow. It occurs naturally in several foods, fruits, and beverages, including bourbon whiskey, black currant, melon, papaya, pineapple, and fresh blackberry.
The compound is characterized by its pleasant creamy and coconut-like aroma. Because of this distinctive sensory profile, it is commonly used as a flavoring ingredient to introduce coconut-like notes into food and beverage formulations. Beyond flavor applications, gamma-nonalactone has also been investigated for its potential to attract multiple species of grain beetle pests, providing possible applications in pest monitoring and control systems.
