N3-PEG1-NH2 (CAS: 464190-91-8), also known as Azido-PEG1-amine, is a heterobifunctional linker featuring both an amino (NH₂) and an azide (N₃) group. The amino group enables reactions with carboxylic acids and activated NHS esters, facilitating the formation of stable amide bonds. The azide group allows for versatile Click Chemistry applications, reacting with alkyne, BCN, and DBCO to form stable triazole linkages. This dual-functionality makes N3-PEG1-NH2 a valuable tool in chemical and biochemical research, including protein labeling, surface modification, and the development of complex biomolecular constructs.
