Description:

WARNING: This product is for research use only, not for human or veterinary use.

KUN 98119, also known as tert-butyl bis(2-hydroxyethyl)carbamate is a PEG Linker. PEG Linkers may be useful in the development of antibody drug conjugates. 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).
