Übersicht

Produktbeschreibung
Bromo-PEG3-t-butyl ester ist ein PEG-Linker, der eine Bromidgruppe und eine t-Butyl-geschützte Carboxylgruppe enthält. Der hydrophile PEG-Spacer erhöht die Löslichkeit in wässrigen Medien. Das Bromid (Br) ist eine sehr gute Abgangsgruppe für nukleophile Substitutionsreaktionen. Die t-Butyl-geschützte Carboxylgruppe kann unter sauren Bedingungen entschützt werden.
