Carbic anhydride (Cat No.:R062373) is a saturated bicyclic anhydride derived from hexahydrophthalic acid. It features a fused-ring structure with reactive anhydride functionality, making it highly useful in organic synthesis and polymer chemistry. Carbic anhydride is widely employed in the production of epoxy curing agents, polyester resins, and specialty polymers. Its chemical reactivity allows for efficient ring-opening reactions with alcohols and amines, facilitating cross-linking and modification processes. This compound is valued for its versatility, stability, and compatibility with applications requiring non-aromatic anhydride moieties.
