General description

The standard in situ coupling reagent for solid phase peptide synthesis [1,2,3,4,5]. This product can replace BOP in all applications without loss of performance. Unlike uronium-based reagents, PyBOP® does not give rise to guanidinated by-products during cyclization and fragment condensation reactions.
