Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly local anesthetics such as lidocaine and related derivatives. Its structure supports the formation of amide bonds critical for bioactive molecule development. It also finds use in the preparation of agrochemicals and organic synthesis where acylated aniline derivatives are required. Due to its stability and reactivity, it serves as a building block in medicinal chemistry for designing compounds with enhanced metabolic resistance and lipophilicity.
