Butyl 3-methylbutanoate (CAS: 109-19-3) is a clear, colorless to pale yellow liquid with a fruity odor. Its molecular weight is approximately 130.23 g/mol. It has a melting point of -30°C, boiling point of 167-168°C, and a density of 0.883 g/cm³. It is slightly soluble in water but miscible with most organic solvents. Chemically, it is stable under normal conditions but can react with strong bases and acids. It has good reactivity with Grignard reagents, making it useful in organic synthesis.

Butyl 3-methylbutanoate (CAS: 109-19-3) is typically synthesized via an esterification reaction between 3-methylbutanoic acid and butanol in the presence of a catalyst such as sulfuric acid or a solid acid. The reaction is carried out at room temperature, and the product is purified by distillation. This method provides a good yield and selectivity, making it a common and efficient synthesis route.

Butyl 3-methylbutanoate (CAS: 109-19-3) finds applications in the fragrance and flavor industry, where it is used as a component in perfumes and food additives due to its pleasant fruity aroma. It is also used in the pharmaceutical industry as a solvent and in the polymer industry as a plasticizer. Additionally, it is utilized in the production of certain types of sensors and semiconductors for its specific chemical properties.

When handling Butyl 3-methylbutanoate (CAS: 109-19-3), it is important to use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. It should be stored in a cool, dry place away from heat and sources of ignition. Fume hoods should be used during handling to minimize inhalation risks. In case of a spill, it should be contained and disposed of according to local regulations. Always consult the Safety Data Sheet (SDS) for specific safety guidelines and emergency procedures.
