Used primarily as an intermediate in the synthesis of specialty esters for lubricants and plasticizers, this compound contributes to improved thermal stability and low-temperature performance in synthetic lubricants. Its branched-chain structure enhances resistance to oxidation and reduces volatility, making it suitable for high-performance engine oils and industrial fluids. It is also employed in the formulation of surfactants and emulsifiers for agrochemicals and coatings, where it helps stabilize emulsions and improve spreading properties. Additionally, derivatives of this acid find use in cosmetic formulations as emollients, providing a non-greasy feel and enhancing skin compatibility.
