Description: XUN 35237, also known as Fmoc-NH-ethyl-SS-propionic NHS ester is a cleavable 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).
