DNP-PEG1 acid linker contains a DNP and carboxylic acid moiety. DNP is used to help understand the chemiosmotic and other membrane transport processes in biochemistry research. The terminal carboxylic acid readily reacts with primary and secondary amine under EDC, DCC, HATU or other amide coupling conditions to form a stable amide bond. PEG spcer bring in extra solubility of the compound in aqueous media.
