Benzotriazol-1-yloxytris(dimethylamino)-phosphonium hexafluorophosphate Usage And Synthesis
Chemical Properties white to off-white powder
Uses Peptide coupling reagent which suppresses racemization.
Uses A peptide coupling reagent. Can be used in the preparation of phenyl esters of amino acids which have been shown to be valuable as blocked derivatives of amino acids in the field of peptide synthesis
Purification Methods Dissolve it in CH2Cl2, dry (MgSO4), filter, concentrate it under a vacuum, then add dry Et2O and filter off the first crop. Add CH2Cl2 to the filtrate and concentrate again to obtain a second crop. The solid is washed with dry Et2O and dried in a vacuum. Also recrystallise it from dry Me2CO/Et2O and check the purity by NMR. Store it in the dark. [Castro et al. Synthesis 751 1976, Nguyen et al J Chem Soc, Perkin Trans I 1915 1987, Coste et al. Tetrahedron Lett 36 4253 1995.]
