Description

Bis(2-Hexadecenoic)Anhydride is a high-purity, unsaturated fatty acid anhydride derived from palmitoleic acid. This specialized chemical intermediate is valued for its reactivity and ability to introduce hydrophobic, long-chain alkenyl functionalities into target molecules. It is primarily sought by manufacturers in the polymer, lubricant additive, and specialty chemical synthesis sectors for creating tailored materials with specific performance characteristics.

Application

• As a key monomer or cross-linking agent in the synthesis of specialty polyesters, polyamides, and alkyd resins.
• In the formulation of advanced lubricant additives and synthetic base oils to enhance viscosity and thermal stability.
• As a chemical intermediate for the production of surfactants and emulsifiers with unique hydrophobic properties.
• In the synthesis of plasticizers and stabilizers for polymer systems requiring improved flexibility and compatibility.
• For the modification of surface coatings and inks to impart specific water-repellent or release properties.
• In research and development for creating novel bioconjugates or pharmaceutical intermediates.
