1,1,1-Trifluoroethyl-PEG5-alcohol is a polyethylene glycol (PEG) derivative characterized by a five-unit PEG chain terminated with a 1,1,1-trifluoroethyl group at one end and a hydroxyl (-OH) group at the other. The trifluoroethyl group is designed to react with lysine and other primary amine groups in proteins, antibodies, and other molecules, facilitating bioconjugation. 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).
