Description: Biotin-PEG4-NHS ester, a biotinylated and PEGylated N-hydroxysuccinimide ester, serves as a linker in the synthesis of proteolysis targeting chimeras (PROTACs) [1]. Target: Others. Smiles: C(CCCC(NCCOCCOCCO CCOCCC(ON1C(=O)CCC1=O)=O)=O)[C@H]2[C@@]3([C@](CS2)(NC(=O)N3)[H])[H]. References: Gadd MS, et al.
