  • Applications

    Tartronic acid (CAS 80-69-3) is primarily used as an intermediate in organic synthesis, enabling the preparation of esters and derivatives. It can also serve as a building block or functional crosslinking node for specialty polymers and polyesters. In coatings and inks, tartronic acid may act as a crosslinking agent or polymer-compatible additive. It is investigated as an intermediate for pharmaceutical and agrochemical synthesis. Additionally, owing to its dihydroxy-dicarboxylic structure, it can function as a chelating agent or stabilizer in cleaning formulations, cosmetics, and metal-processing applications, subject to formulation limits and regulations.
