Description

Butyl Butyrate is a versatile ester compound valued for its fruity, pineapple-like aroma and excellent solvent properties. This clear, colorless liquid is a key ingredient in flavor and fragrance formulations, while also serving as an effective, high-boiling solvent for resins, polymers, and cellulose derivatives. It is essential for manufacturers in the flavor & fragrance, coatings, and specialty chemical industries seeking reliable, high-purity intermediates and solvents.

Application

• Flavor & Fragrance Agent: Used as a synthetic flavoring substance in food products and as a fragrance component in perfumes, cosmetics, and personal care items for its characteristic fruity note.
• Industrial Solvent: Acts as a high-boiling point solvent for cellulose derivatives, resins, polymers, and oils in the production of coatings, inks, and adhesives.
• Chemical Intermediate: Serves as a building block in organic synthesis for the production of more complex esters, pharmaceuticals, and agrochemicals.
• Plasticizer & Additive: Employed as a plasticizer and processing aid in polymer and rubber manufacturing to improve flexibility and workability.
• Extraction Solvent: Utilized in the extraction of natural products, essential oils, and other organic compounds in laboratory and industrial processes.

Quality Control

Our Butyl Butyrate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. It is produced in compliance with relevant industry standards, including FEMA and FCC guidelines for food-grade applications where specified. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and physical properties is provided with every shipment to guarantee product integrity and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents, acids, and bases. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to prevent evaporation and moisture absorption.
