Product Description	Azido-PEG3-t-butyl ester is a PEG derivative containing an azide group and a t-butyl ester. The hydrophilic PEG spacer increases solubility in aqueous media. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The t-butyl protected carboxyl group can be deprotected under acidic conditions.
