Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients that require selective reactivity and stability. Its structure allows for efficient coupling in peptide-like bond formations, making it valuable in medicinal chemistry for constructing complex molecules. Also employed in the production of specialty polymers and functional coatings where controlled release or cross-linking properties are needed. Due to its amine-reactive ester functionality, it is useful in bioconjugation techniques for labeling and immobilizing biomolecules.
