(3-Hydroxy-3H-1,2,3-triazolo[4,5-b]pyridinato-O)tri-1-pyrrolidinylphosphonium hexafluorophosphate Chemical Properties,Usage,Production

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

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).

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.
