Isobutyronitrile is primarily used as an intermediate in the synthesis of various chemicals, including pharmaceuticals, agrochemicals, and specialty compounds. It serves as a building block in the production of pesticides, herbicides, and fungicides, contributing to crop protection and agricultural efficiency. In the pharmaceutical industry, it is utilized in the manufacturing of active pharmaceutical ingredients (APIs) and other drug-related compounds. Additionally, isobutyronitrile finds application in organic synthesis, where it acts as a precursor for the preparation of other nitriles, amines, and carboxylic acids. Its role in these processes highlights its importance in industrial chemistry and material science.
