Bromo-PEG5-azide

CAS number:1402411-90-8    molecular formula:C12H24BrN3O5

overview

compound introduction

Bromo-PEG6-azide 是一种 PROTAC linker,属于 PEG 类。可用于合成 PROTAC 分子。Bromo-PEG5-azide 是一种点击化学试剂。它含有 Azide 基团,可以和含有 Alkyne 基团的分子发生铜催化的叠氮-炔环加成反应(CuAAc)。它还可以和含有 DBCO 或 BCN 基团的分子发生环张力驱动的炔-叠氮环加成反应 (SPAAC)。 Bromo-PEG5-azide is a PEG derivative containing a bromide group and a terminal azide. The hydrophilic PEG spacer increases solubility in aqueous media. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage.
