Used primarily in the production of melamine-formaldehyde resins, which are key in manufacturing durable laminates, countertops, and kitchenware due to their heat resistance and scratch resistance. Commonly found in decorative surfaces for furniture and cabinetry. Also used as a flame retardant in coatings and plastics, and in some industrial adhesives. Historically misused as a food adulterant due to high nitrogen content, though this is now strictly regulated.
