General description
4-Nitrophenyl chloroformate, also known as p-nitrophenyl chloroformate, is a coupling agent used in the synthesis of ureas, carbamates, and carbonates. It is also used as a building block in solid-phase peptide synthesis (SPPS) to obtain altered side chain functionalities in peptides.
Application
4-Nitrophenyl chloroformate is used as:
- A coupling agent to link the drug molecule with the polyrotaxane carrier molecule
- As an activated ester reagent that enables the covalent coupling of a peptide onto a macromer, such as oligo(poly(ethylene glycol) fumarate) (OPF)
