Fmoc-NH-PEG12-CH2CH2COOH (also known as Fmoc-NH-PEG12-propionic acid) is a protected form of propionic acid modified with Fmoc (9-FLUORENYLME- THOXYCARBONYL) and PEG12 (polyethylene glycol 12). It is useful in the peptide synthesis and biomolecules synthesis. For example, it can be used for tether peptides to proteins or other large biomolecules (such as nucleic acids). The attachment of the hydrophobic peptide, NH2-PEG12 can effectively reduce aggregation.
Viscous, colorless to yellow liquid
