  • Uses:

Fmoc-N-amido-PEG8-acid (Fmoc-NH-PEG8-COOH) is a PEG derivative containing an Fmoc-protected amine and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The Fmoc group can be deprotected under basic condition to obtain the free amine which can be used for further conjugations. The terminal carboxylic acid can be reacted with primary amine groups in the presence of activators (e.g. EDC, or DCC) to form a stable amide bond.

Numerous applications have used Fmoc-N-amido-PEG8-acid. For example, it is a cleavable ADC linker used in the synthesis of antibody-drug conjugates (ADCs)[1].
