Basic Description Synonyms 166108-71-0|[2-[2-(Fmoc-amino)ethoxy]ethoxy]acetic acid|Fmoc-NH-PEG2-CH2COOH|1-(9H-FLUOREN-9-YL)-3-OXO-2,7,10-TRIOXA-4-AZADODECAN-12-OIC ACID|Fmoc-8-amino-3,6-dioxaoctanoic acid|8-(Fmoc-amino)-3,6-dioxaoctanoic acid|{2-[2-(Fmoc-amino)ethoxy]ethoxy}acetic Specifications & Purity 98% Storage Temp Store at -20°C Shipped In Ice chest + Ice pads Product Description Fmoc-NH-PEG2-CH2COOH 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.
