Fmoc-NH-PEG2-COOH (CAS No.: 872679-70-4) is a versatile PEG linker featuring an Fmoc-protected amine and a terminal carboxylic acid. The Fmoc group can be removed under basic conditions to reveal a free amine, enabling further conjugation. The carboxylic acid group readily reacts with primary amines in the presence of activators like EDC or HATU to form stable amide bonds.
This linker serves as a cleavable ADC linker in the synthesis of antibody-drug conjugates (ADCs), facilitating precise payload delivery. Additionally, it functions as a PEG-based PROTAC linker, used in the development of PROTACs.
Biopharma PEG offers a wide range of PEG linkers on both lab and commercial scales. Email at sales@biochempeg.com and start using a superior product for your next product R&D project.
