Used in the synthesis of nylon-6,6, this compound serves as a key intermediate in polymer production. It contributes to the formation of polyamides by reacting with diamines or diacids, enhancing thermal stability and mechanical strength of the resulting plastics. Also explored in pharmaceutical research for its potential role in prodrug design due to its amide-forming capability and biocompatibility. Additionally, it finds use in modifying peptides and proteins to improve solubility and bioavailability.
