Application:

1H-Benzotriazol-1-yloxytripyrrolidinophosphonium Hexafluorophosphate (PyBOP) (CAS: 128625-52-5)is one of the most convenient peptide coupling reagents utilized in solid phase peptide synthesis without carcinogenic by-products. It is also used as a substitute for the (benzotriazol-1-yloxy)tris(dimethylamino)phosphonium hexafluorophosphate (BOP) reagent. It has reactivity similar to BOP, but its byproduct is not highly carcinogenic. PyBOP is especially suitable for solid-phase peptide synthesis, avoids racemization. In contrast to uronium-based coupling reagents, PyBOP does not form guanidinated byproducts when used in excess. This makes it useful in fragment condensation reactions and head-to-tail cyclizations.
Analogs of BOP coupling reagents, but do not form carcinogens HMPA is a by-product. May be used in place of BOP in peptide synthesis without loss of coupling efficiency. Coupling reactions are rapid, being nearly complete within a few minutes. Especially useful for cyclization steps for the activation of hindered amino acid.
Reagent for: Synthesis of single labeled oligonucleotides that fluoresce upon matched hybridization; Generation of endocrine disruptor chemical binders; Cycloaddition to template-assembled multivalent peptide conjugates.
