Used as a catalyst and solvent in polyurethane foam production, enhancing reaction efficiency and foam stability. Commonly applied in the manufacturing of flexible and rigid foams for insulation, bedding, and automotive materials. Also serves as an intermediate in organic synthesis, particularly in pharmaceuticals and agrochemicals, due to its ability to facilitate ring-forming reactions and act as a building block in complex molecule assembly. Its volatility and basicity make it suitable for use in gas treatment processes to remove acidic components.
