Used primarily as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of selective monoamine oxidase inhibitors (MAOIs) for the treatment of neurological disorders such as depression and Parkinson’s disease. It also serves as a building block in the preparation of agrochemicals and bioactive molecules due to its ability to form stable hydrazone derivatives. Its reactivity and structural configuration make it valuable in medicinal chemistry for constructing nitrogen-containing heterocycles.
