Description

Butanoic Acid, 3-Methyl-, 1,3-Dimethylbutyl Ester CAS NO 5332-89-8 is a branched-chain fatty acid ester valued for its unique organoleptic properties and solvent characteristics. This compound is significant for its role as a flavor and fragrance ingredient, offering fruity and green notes to formulations. It is primarily needed by manufacturers in the flavor & fragrance, food, and specialty chemical industries seeking high-purity intermediates.

Application

• Flavor & Fragrance Industry: Used as a key intermediate or component in the synthesis of complex aroma chemicals, imparting fruity, green, or waxy nuances to perfumes, cosmetics, and personal care products.
• Food Additives: Serves as a flavoring agent in food products, contributing to the taste profile of items like candies, beverages, and baked goods.
• Specialty Solvents: Acts as a high-boiling, low-volatility solvent for resins, coatings, and inks, particularly where specific solvency power and mild odor are required.
• Chemical Synthesis: Employed as a versatile building block or esterification agent in organic synthesis for pharmaceuticals and agrochemicals.
• Plasticizers & Polymer Additives: Functions as a co-monomer or additive to modify the flexibility and processing characteristics of certain polymers.
