m-PEG24-azide（Cat No.:I045912）is a monofunctional polyethylene glycol derivative featuring a methoxy cap on one end and a terminal azide on the other. The azide group enables efficient bioorthogonal click chemistry with alkynes, while the long PEG24 chain provides excellent hydrophilicity, flexibility, and spacing. This extended length reduces steric hindrance, enhances solubility, and improves accessibility in complex biological systems. m-PEG24-azide is widely employed in biomaterials, drug delivery, imaging, and chemical biology, where it serves as a versatile building block for controlled conjugation, surface modification, and multifunctional molecular design.
