Product Name: PyBOP®

Product Number: KPC-1068-PI

Synonym(s): Benzotriazol-1-yl-oxytripyrrolidinophosphonium hexafluorophosphate (Benzotriazol-1-yloxy)tripyrrolidinophosphonium hexafluorophosphate

Application: Analogue of the BOP coupling reagent which does not form carcinogenic HMPA as by-product. Coupling reactions are rapid, being nearly complete within a few minutes. May be used in place of BOP in peptide synthesis without loss of coupling efficiency. Especially useful for cyclization steps for the activation of hindered amino acid.
