WGK Germany 3 RTECS VB2010000 FLUKA BRAND F CODES 9-21 TSCA Yes HS Code 2933490090N-Ethoxycarbonyl-2-Ethoxy-1,2-Dihydroquinoline (EEDQ) (CAS: 16357-59-8), Peptide condensing agent with little or no racemization. Amidation coupling reagent. In the synthesis of peptides. 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. EEDQ is an irreversible membrane-bound receptor antagonist. polypeptide synthesis condensing agent, commonly used for condensation of amino and carboxyl groups. The coupling agent in polypeptide synthesis, the classic mixed acid anhydride method polypeptide condensing agent, has a mild and effective effect. Irreversible membrane-bound receptor antagonists. Irreversible membrane-shaped receptor antagonists It is used in synthetic chemistry, discovery, process R&D. It also acts as coupling reagents.
