Used as an intermediate in the synthesis of biologically active compounds, particularly in the development of pharmaceutical agents. It serves as a building block for sulfonamide-based drugs, which are known for their antimicrobial, antiviral, and enzyme inhibitory properties. Its structure allows for easy modification in medicinal chemistry, making it valuable in creating libraries of compounds for drug discovery. Commonly employed in reactions where the ethyl carbamate group can be cleaved or transformed to introduce amine functionalities in target molecules.
