1. Polyurethane Industry
As a catalyst, it is mainly used in rigid polyurethane foams (such as refrigerator insulation layers and panels), and also in flexible foams, adhesives, and coatings. It provides good initial flowability and a uniform cell structure.

2. Epoxy Resins
It is commonly used as a tertiary amine curing agent or an accelerator in anhydride curing systems, accelerating resin curing. It is applied in fields such as electronic potting materials, floor coatings, and marine paints.

3. Organic Synthesis and Pharmaceuticals
It serves as a dehydrogenation (or dehydrohalogenation) catalyst, an acid neutralizing agent, and a key intermediate in organic synthesis.

4. Quaternary Ammonium Salt Synthesis
It is an important raw material for the production of quaternary ammonium compounds (such as the powerful disinfectant “benzalkonium chloride”).

5. Other Specialized Fields
It is used as an accelerator for embedding samples in electron microscopy and as a corrosion inhibitor in metal processing.
