Description

1-Pentanol ( CAS 71-41-0 ), also known as primary amyl alcohol, is a straight-chain aliphatic alcohol used as a solvent, chemical intermediate, and flavoring agent across food, cosmetic, and polymer industries. FEMA 2056 status confirms its recognized use in flavor applications. Its moderate chain length positions it between short-chain and fatty alcohols, making it useful where both solvency and mild odor character are required. In flavor formulations, 1-pentanol contributes a mild, fusel-like note and functions as a carrier or co-solvent for flavor concentrates in food and beverage products. Polymer manufacturers use it as a reactive intermediate in the synthesis of plasticizers and esters, particularly amyl acrylate and amyl acetate. In personal care, it acts as a solvent and viscosity modifier. It is utilized in emulsions and fragrance bases where a light, non-greasy carrier is needed. It also serves as a process solvent in pharmaceutical and specialty chemical synthesis. This material is operationally relevant where controlled polarity and low water miscibility are required. 1-Pentanol is supplied as a clear liquid in drums and IBC containers. Food-grade material meeting FCC specifications is available for flavor and fragrance applications, while technical-grade product serves industrial solvent and synthesis uses.
