Used as a curing agent and crosslinking agent in epoxy resin systems, enhancing thermal stability and mechanical strength of the final product. Its rigid cyclohexane backbone and multiple amine groups enable efficient network formation, making it suitable for high-performance coatings, adhesives, and composite materials. Also employed in the synthesis of specialty polymers and as a building block in pharmaceutical intermediates where stereochemistry plays a critical role in activity. Its hydrochloride form improves solubility and handling in aqueous systems.
