3,3′-Dimethylglutaric anhydride（Cat No.:R070522）is a cyclic dicarboxylic acid anhydride derived from 3,3-dimethylglutaric acid, with the molecular formula C7H10O3. It features a five-membered anhydride ring with two methyl groups at the 3-position, introducing steric bulk and influencing its reactivity. This compound is commonly used as a reagent or intermediate in organic synthesis, particularly in the preparation of polymers, pharmaceuticals, and agrochemicals. Its anhydride functionality readily undergoes ring-opening reactions with nucleophiles such as amines or alcohols, making it useful for modifying surfaces, synthesizing functionalized monomers, and developing bioactive molecules.
