Used primarily as a reactive intermediate in the synthesis of oil-soluble dispersants for lubricant additives. It reacts with polyamines to form dispersant agents that help keep engine deposits suspended in motor oil, preventing sludge buildup and maintaining engine cleanliness. Commonly employed in the formulation of automotive and industrial lubricants to improve performance and extend oil life. Also utilized in the production of corrosion inhibitors and emulsifiers in specialty chemical applications.
