Description

Isopropyl Butyrate CAS NO 638-11-9 is a clear, colorless liquid ester characterized by a fruity, apple-like aroma. This compound is valued for its role as a versatile flavor and fragrance intermediate, as well as a high-purity solvent for specialized applications. It is primarily sought by manufacturers in the flavor & fragrance, food & beverage, and fine chemical synthesis industries.

Application

• Flavor and Fragrance Agent: Used as a key ingredient or building block for creating fruity, apple, and berry flavor profiles in food, beverages, and confectionery, as well as in perfumes and cosmetic formulations.
• High-Purity Solvent: Employed as a solvent in the synthesis of pharmaceuticals, agrochemicals, and other specialty organic compounds where high volatility and specific solvency properties are required.
• Chemical Intermediate: Serves as a starting material or intermediate in organic synthesis for producing more complex esters, pharmaceuticals, and fine chemicals.
• Industrial Applications: Functions as a component in industrial cleaners, degreasers, and coating formulations where rapid evaporation is beneficial.

Quality Control

Our Isopropyl Butyrate is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC), to ensure it meets precise purity and compositional specifications. Certificates of Analysis (COA) documenting identity, assay, and impurity profiles are available for all shipments. We can supply grades tailored to meet FEMA, FCC, and other relevant industry standards upon request.

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.
