Used primarily as an intermediate in organic synthesis, especially in the development of pharmaceuticals and biologically active compounds. Its amine and sulfinyl functional groups allow for versatile reactivity, enabling use in the preparation of sulfoxide-containing molecules with potential pharmacological activity. It has been explored in the synthesis of analogs related to sulfur-containing natural products and drugs, where the sulfinyl group can influence bioavailability and metabolic stability. Additionally, it serves as a building block in the design of enzyme inhibitors and receptor ligands due to its structural similarity to other bioactive amines.
