CAS 109-19-3: Butyl isovalerate
Description:Butyl isovalerate, with the CAS number 109-19-3, is an ester formed from the reaction of butanol and isovaleric acid. It is characterized by its fruity odor, which makes it useful in the flavor and fragrance industries. The compound is typically a colorless to pale yellow liquid at room temperature and is known for its relatively low volatility. Butyl isovalerate is soluble in organic solvents but has limited solubility in water due to its hydrophobic nature. Its chemical structure features a butyl group attached to the isovalerate moiety, contributing to its unique properties. The substance is used in various applications, including as a flavoring agent in food products and as a fragrance component in perfumes and cosmetics. Additionally, it may be involved in chemical synthesis and research applications. Safety data indicates that, while it can be irritating to the skin and eyes, proper handling and usage guidelines can mitigate potential hazards.
