Applications & Use Cases
- ▸ Diacid monomer for polycondensation into nylon-6,9 polyamides, co-polyamides, and high-performance polyester and polyurethane resins.
- ▸ Feedstock for azelate diester plasticizers and synthetic lubricant base stocks (e.g., di-2-ethylhexyl azelate) valued for low-temperature flexibility and oxidative stability.
- ▸ Active and functional ingredient in cosmetic and personal-care formulations, including brightening, anti-blemish, and skin-conditioning leave-on and rinse-off products.
- ▸ Corrosion-inhibiting additive and intermediate in metalworking fluids, coatings, and rust-preventive formulations where dibasic acids passivate metal surfaces.
- ▸ Building block for alkyd and powder-coating resins and for specialty surfactant and emulsifier synthesis.
