Description

Methyl Isobutyrate CAS NO 547-63-7 is a clear, colorless ester with a characteristic fruity odor, valued for its role as a versatile chemical intermediate and flavor/fragrance component. Its high volatility and favorable solvent properties make it an efficient and reactive building block in organic synthesis. This compound is essential for manufacturers in the flavor & fragrance, agrochemical, and pharmaceutical industries seeking reliable, high-purity raw materials.

Application

• Flavor and Fragrance Agent: Used as a synthetic fruit flavoring (e.g., apple, strawberry) in food products and as a fragrance component in perfumes and cosmetics.
• Chemical Synthesis Intermediate: Serves as a key precursor in the production of other esters, pharmaceuticals, and fine chemicals.
• Agrochemical Formulations: Employed as a solvent or intermediate in the manufacture of pesticides and herbicides.
• Industrial Solvent: Acts as a solvent for resins, cellulose derivatives, and oils in coatings and specialty cleaning formulations.
• Polymer Industry: Can be used as a monomer or co-monomer in specific polymerization processes.
• Research & Development: Utilized in laboratories for organic synthesis and as a standard in analytical chemistry.
