2,2-Bis(hydroxymethyl)propionic acid, often abbreviated as DMPA and identified by CAS number 4767-03-7, is a chemical compound of significant industrial importance. Its unique molecular structure, featuring two primary hydroxyl groups and a tertiary carboxylic acid group, makes it an exceptionally versatile building block for a multitude of applications, particularly in the fields of electronic chemicals, advanced coatings, and specialty polymers. As a leading manufacturer and supplier of DMPA in China, we aim to provide clarity on its properties and extensive applications.

Physically, DMPA is typically a white to off-white crystalline solid. It boasts a molecular weight of approximately 134.13 g/mol and a high melting point, often in the range of 185-190°C, indicative of its stable crystalline structure. The presence of both hydroxyl and carboxylic acid functionalities allows DMPA to readily participate in esterification, etherification, and polymerization reactions. This bifunctionality is key to its widespread use.

One of the most prominent applications of DMPA is in the formulation of waterborne polyurethanes and polyesters. The carboxylic acid group, upon neutralization with amines, imparts water dispersibility to the polymer backbone, enabling the creation of environmentally friendly, low-VOC coatings and adhesives. In the electronics sector, DMPA serves as a critical component in photoresist formulations, contributing to the precise patterning required for semiconductor manufacturing. Its controlled reactivity and the properties it confers on polymers make it invaluable for these high-tech applications.

For professionals seeking to purchase DMPA, understanding its purity and source is vital. We offer DMPA with a minimum purity of 97%, ensuring that it meets the rigorous standards for electronic and specialty chemical applications. As a dedicated China manufacturer and supplier, we provide competitive pricing and reliable supply chains.
