Used primarily as an intermediate in the synthesis of various pharmaceuticals, particularly in the production of antihistamines and other therapeutic agents. It serves as a building block for creating compounds with potential anti-inflammatory and analgesic properties. Additionally, it finds application in the manufacture of agrochemicals, such as herbicides and fungicides, due to its reactivity and ability to form stable derivatives. In industrial settings, it is utilized as a corrosion inhibitor, helping to protect metal surfaces from degradation. Its role in organic synthesis extends to the production of specialty chemicals, including dyes and polymers, where it acts as a precursor or modifying agent.
