Description

Allylsuccinic Anhydride CAS NO 7539-12-0 is a reactive, unsaturated cyclic anhydride characterized by its allylic functionality. This unique structure makes it a valuable intermediate for introducing both carboxylic acid and reactive alkene groups into target molecules, enabling the synthesis of specialized polymers, resins, and fine chemicals. It is primarily sought by R&D chemists and process engineers in the polymer, coatings, and pharmaceutical intermediate sectors for applications requiring tailored cross-linking or functionalization.

Application

• Polymer Modification: As a comonomer or cross-linking agent in the production of alkyd resins, polyesters, and epoxy curing agents to enhance flexibility and chemical resistance.
• Fine Chemical Synthesis: A key building block for synthesizing pharmaceutical intermediates, agrochemicals, and specialty surfactants.
• Adhesive & Sealant Formulations: Imparts improved adhesion and durability in high-performance adhesive systems.
• Coating Industry: Used in the formulation of advanced industrial and protective coatings to modify film properties.
• Research & Development: Serves as a versatile reagent in organic synthesis for Diels-Alder reactions and other cycloadditions.
• Lubricant Additives: Potential use in the synthesis of derivatives that act as viscosity modifiers or anti-wear agents.
