Used primarily as a plasticizer intermediate in the production of high-performance polymers and resins. It improves flexibility, durability, and low-temperature performance in coatings, adhesives, and sealants. Its branched structure enhances hydrolytic stability and resistance to oxidation, making it suitable for use in demanding environments. Also employed in the formulation of synthetic lubricants and functional fluids where thermal stability and low volatility are required. Additionally, it serves as a building block in specialty chemicals for agrochemicals and pharmaceuticals due to its bifunctional alcohol groups.
