PyOxim

CAS: 153433-21-7

A highly efficient coupling reagent. PyOxim is more reactive than TBTU or PyBOP. It is about as reactive as COMU; and, as COMU, PyOxim is safer to handle and less allergenic than HOBt-based coupling reagents. As PyOxim represents a phosphonium-type coupling reagent, N-terminal guanidinylation as a side-reaction during coupling is avoided.

PyOxim

CAS: 153433-21-7

PyOxim is a phosphonium salt used as a coupling reagent for peptide synthesis. PyOxim is the phosphonium derivative of Oxyma, and is stable, safe, soluble in DMF and most organic solvents. PyOxim is extremely efficient, achieving high yields and good racemisation suppression; it is particularly effective with sterically hindered peptides and cyclic peptides.
