Isobutyl butyrate(CAS: 539-90-2)

Isobutyl butyrate (CAS: 539-90-2) is a clear, colorless to light yellow liquid with a fruity odor. It has a molecular weight of approximately 154.23 g/mol. It is slightly soluble in water but miscible with most organic solvents. Isobutyl butyrate is relatively stable but can react with strong acids and bases. It is used as a food flavoring agent and in perfumes.

Isobutyl butyrate (CAS: 539-90-2) is typically synthesized through a Fischer esterification reaction between isobutanol and butyric acid. The reaction is usually catalyzed by an acid, such as sulfuric acid, and the mixture is heated. The process yields a product that is then purified by distillation. The reaction is selective and provides a high yield of the desired ester.

Isobutyl butyrate (CAS: 539-90-2) is widely used in the food and beverage industry as a flavoring agent, particularly for fruits and confectionery. It is also used in the perfume and fragrance industry for its fruity aroma. Additionally, it is used in some pharmaceutical applications for flavoring oral medications and in the polymer industry as a plasticizer.

When handling Isobutyl butyrate (CAS: 539-90-2), proper personal protective equipment (PPE) should be worn, including gloves, goggles, and a lab coat. This compound should be stored in a tightly sealed container in a cool, well-ventilated area, away from direct sunlight and heat. It is flammable and should not be exposed to open flames or sparks. In case of a spill, it should be handled carefully, and appropriate cleanup procedures should be followed as outlined in the Safety Data Sheet (SDS).
