amine peg thiol (mw 3400)

Amine-PEG-thiol (MW 3400) is a polyethylene glycol (PEG)-based linker molecule containing an amine group and a thiol group. It serves as an essential component in the synthesis of proteolysis targeting chimeras (PROTACs)[1].

Stearic acid-PEG-CH2CO2H (MW 3400) 是一种亲脂性硫醇反应性PEG聚合物。硬脂酸部分用于包封疏水性治疗剂，而PEG链提高整体水溶性及生物相容性。在活化剂（如HATU或EDC）存在下，羧酸（-COOH）与胺（-NH2）通过缩合产生稳定的酰胺键。试剂级，仅供研究使用。
