Widely used in the production of melamine-formaldehyde resins, which are key in manufacturing durable laminates, countertops, and kitchenware due to their heat resistance and hardness. Commonly found in adhesives, coatings, and surface finishes for wood products. Also used as a flame retardant in textiles and plastics, and in some industrial applications as a crosslinking agent. Its high nitrogen content has led to misuse in food adulteration, though this is illegal and hazardous.
