Description

n-Butyl Valerate CAS NO 591-68-4 is a clear, colorless ester with a characteristic fruity odor, widely used as a versatile intermediate and flavor/fragrance component. Its value lies in its excellent solvent properties and its role as a building block for synthesizing more complex chemical compounds. This product is essential for manufacturers in the flavor & fragrance, pharmaceutical, and specialty chemical industries seeking reliable, high-purity raw materials.

Application

• Flavor and Fragrance Agent: Used as a synthetic flavoring ingredient in food products and as a fragrance component in perfumes, cosmetics, and personal care items for its fruity, apple-like notes.
• Chemical Intermediate: Serves as a key building block in organic synthesis for the production of pharmaceuticals, agrochemicals, and other specialty esters.
• Specialty Solvent: Employed as a solvent for resins, cellulose derivatives, and in various coating formulations due to its favorable evaporation rate and solvency power.
• Plasticizer Precursor: Acts as an intermediate in the manufacture of plasticizers and other polymer additives.
• Lubricant Additive: Used in the formulation of synthetic lubricants and functional fluids.
