General description

2-Ethoxy-1-ethoxycarbonyl-1,2-dihydroquinoline(EEDQ) is a stable, and readily available reagent used to prepare amides and peptides in high yields. At ambient temperature, EEDQ is soluble in an aqueous medium containing organic solvents but insoluble in water. It is used as a coupling agent in peptide synthesis.

Application

2-Ethoxy-1-ethoxycarbonyl-1,2-dihydroquinoline is used as a coupling agent:
  • In the regioselective quaternization of chitosan and its amphiphilic derivatives.
  • In the preparation of amide-type S-MA derivative-modified QCM sensors.

There is strong demand for cell separation methods that do not decrease cell activity or modify cell surfaces. Here, new temperature-modulated cell-separation columns not requiring cell-surface premodification are described. The columns were packed with temperature-responsive cationic polymer hydrogel-modified silica beads.
