This chemical is primarily used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and bioactive compounds. It plays a key role in the development of peptide-based drugs, where the tert-butoxycarbonyl (Boc) group serves as a protective group for amines during synthesis. The presence of the chloro and carboxylic acid functional groups allows for further chemical modifications, making it valuable in creating complex molecules. It is also utilized in research settings for the development of new therapeutic agents, especially in the fields of oncology and immunology. Its stability and reactivity make it a versatile building block in medicinal chemistry.
