Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research. It serves as a building block for sulfonamide-based drugs, which are known for their antimicrobial and enzyme-inhibiting properties. Its structure allows for easy modification in drug design, making it valuable in developing compounds with potential antiviral, anti-inflammatory, or anticancer activity. Commonly employed in medicinal chemistry for introducing the 4-isopropylpiperazine moiety linked to aromatic sulfones, enhancing solubility and receptor binding in target molecules.
