Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It serves as a building block for the preparation of various nitrogen-containing compounds, including active ingredients in herbicides and plant growth regulators. Also utilized in the synthesis of specialty polymers and surfactants due to its reactivity and solubility properties. Its hydrochloride form enhances stability and handling in industrial processes, and provides a less basic environment suitable for base-sensitive reactions.
