Dimethylolpropionic Acid (DMPA), identified by CAS number 4767-03-7, is a difunctional molecule that plays a pivotal role in the synthesis of various polymers and fine chemicals. Its unique structure, featuring both hydroxyl and carboxylic acid groups, grants it remarkable versatility, making it a highly sought-after intermediate in the chemical industry. As a leading manufacturer and supplier in China, we offer high-purity DMPA that serves a broad spectrum of industrial applications, from advanced coatings to specialized resins.

Chemically, DMPA is characterized by its molecular formula C5H10O4 and a molecular weight of 134.13 g/mol. It typically presents as a white crystalline powder with a high purity level, often exceeding 99.0%. This crystalline nature, combined with its relatively low density (0.84 g/cm³), makes it easy to handle and incorporate into various chemical processes. The presence of two primary hydroxyl groups allows for esterification or etherification reactions, while the tertiary carboxylic acid group can be neutralized to introduce water solubility or react in condensation polymerizations. This dual functionality is precisely what makes DMPA so valuable to product formulators and chemical engineers.

One of the most significant applications of DMPA is in the formulation of waterborne polyurethane dispersions (PUDs). By neutralizing the carboxylic acid group, manufacturers can create stable, high-solid dispersions of polyurethanes in water. These PUDs are environmentally friendly alternatives to solvent-based systems, widely used in coatings for wood, metal, and textiles, as well as in adhesives and textile finishes. The chemical stability and performance characteristics imparted by DMPA make it indispensable for these demanding applications.

Beyond PUDs, DMPA serves as a crucial component in the preparation of water-solution alkyd resins, polyester resins, and various specialty chemicals. Its ability to introduce controlled hydrophilicity and reactive sites makes it a preferred choice for creating polymers with specific functional properties. Industries such as leather manufacturing, printing inks, and even pharmaceutical intermediates benefit from the unique contributions of DMPA to their product formulations. For businesses looking to source this critical intermediate, partnering with a reliable manufacturer like us ensures consistent quality and competitive pricing.
