Used primarily as an intermediate in the synthesis of pharmaceuticals, dyes, and other organic compounds. It serves as a building block in the production of sulfa drugs, which are antibiotics effective against bacterial infections. Additionally, it is employed in the manufacturing of plasticizers, resins, and rubber chemicals, enhancing their properties. In industrial applications, it acts as a corrosion inhibitor and stabilizer in various chemical processes. Its role in organic synthesis is crucial for creating complex molecules with specific functional groups.
