Dimethyl citric acid（Cat No.:I044780）is a methylated derivative of citric acid, in which two of the hydroxyl groups are esterified with methyl groups. This modification alters its solubility and reactivity, making it useful in organic synthesis, polymer chemistry, and materials science. Dimethyl citric acid can serve as an intermediate in the preparation of biodegradable polymers, chelating agents, or surface-modifying compounds. Its structural similarity to citric acid retains mild acidity and metal-binding capabilities, allowing applications in catalysis, formulations, and coatings. It is also studied for its potential in green chemistry and bio-based material development.
