Description

Butyl Isobutyrate is a versatile ester valued for its pleasant, fruity odor and excellent solvent properties. This high-purity chemical is essential for formulators requiring a reliable, high-volatility component with low odor thresholds. It is primarily sought after by manufacturers in the flavor & fragrance, coatings, and specialty chemical industries for its role as a key intermediate and solvent.

Application

• Flavor & Fragrance Agent: Used as a synthetic flavoring substance and fragrance component in perfumes, cosmetics, and food products for its characteristic fruity, apple-like aroma.
• Solvent & Diluent: Acts as an effective solvent for resins, cellulose esters, and oils in the formulation of paints, coatings, and inks, prized for its high volatility and good solvency.
• Chemical Intermediate: Serves as a crucial building block in organic synthesis for the production of more complex esters, pharmaceuticals, and agrochemicals.
• Plasticizer & Additive: Employed as a plasticizer in certain polymer systems and as a flow-enhancing additive in various industrial formulations.
• Cleaning & Degreasing Formulations: Utilized in specialty cleaning products and degreasers due to its ability to dissolve organic compounds.

Quality Control

Our Butyl Isobutyrate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including gas chromatography (GC), to ensure it meets precise specifications for identity, purity, and odor profile. Certificates of Analysis (COA) are provided as standard, confirming compliance with relevant industry standards such as FCC for food-grade applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and open flame. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Recommended storage temperature is 15-25°C.
