[Chemical Properties]

(3-Hydroxy-3H-1,2,3-triazolo[4,5-b]pyridinato-O)tri-1-pyrrolidinylphosphonium hexafluorophosphate is white to off-white crystalline powder
[Uses]

(3-Hydroxy-3H-1,2,3-triazolo[4,5-b]pyridinato-O)tri-1-pyrrolidinylphosphonium hexafluorophosphate is used as a coupling reagent in solid phase peptide synthesis. It is preferred over HATU, because it does not side react at the N-terminus of the peptide. Compared to the HOBt derivates, PyAOP (and HOAt in general) are more reactive due to the additional nitrogen.
[Uses]

PyAOP is a phosphonium salt used as a coupling reagent in solid-phase peptide synthesis, without undergoing side reactions with the amino terminus. PyAOP is a derivative of HOAt (H805070).
