3. Application Scope and Usage
Isobutyric acid is widely used in the production of flavors and fragrances due to its sharp, pungent odor. It is also utilized in the synthesis of pharmaceuticals, plastics, and rubber chemical intermediates. In the food industry, it serves as a flavor enhancer and acidulant. Additionally, it finds applications in the manufacture of pesticides and as a raw material for the production of esters and amines
4. Package and Storage
Isobutyric acid is typically packaged in 180 kg or 200 kg net weight drums or 25 kg plastic drums for transportation and storage. It should be stored in a cool, dry place away from heat sources and protected from moisture. The storage area should be well-ventilated to prevent the accumulation of fumes. The drums should be kept tightly closed to prevent contamination and evaporation
