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.

We are committed to bringing you greener alternative products, which adhere to one or more of the 12 Principles of Green Chemistry. PyBOP is widely used as a substitute for the BOP, with the aim of avoiding formation of hexamethylphosphoric triamide (HMPA) which is a carcinogenic side product. Click here for more information.
