Description: KUN45014, also known as Azido-PEG4-t-Boc-hydrazide is a PEG derivative containing an azide group and a Boc-protected hydrazide. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The Boc can be deprotected under mild acidic conditions to form a reactive hydrazide, which can then be coupled with various carbonyl groups. This product has no formal name at the moment. For the convenience of communication, a temporary code name was therefore proposed according to MedKoo Chemical Nomenclature (see web page: https://www.medkoo.com/page/naming).
