Terephthalic acid, monohydroxyethyl ester sodium salt (Cat No.: M048178) is a partially esterified derivative of terephthalic acid in which one carboxylic acid group is converted to a hydroxyethyl ester and the other to a sodium carboxylate salt. This amphiphilic structure offers both hydrophilic and lipophilic properties, making it useful as an intermediate in polyester synthesis, surfactants, or dispersing agents. It plays a role in modifying polymer properties or enhancing compatibility in copolymer systems, coatings, or formulations requiring ionic functionality and controlled reactivity.
