About (Benzotriazol-1-yloxy)tris(dimethylamino)phosphonium hexafluorophosphate, 97%

(Benzotriazol-1-yloxy)tris(dimethylamino)phosphonium hexafluorophosphate (CAS 56602-33-6) is an azole building block offered by Vaqora Chemicals at a purity of 97%. Formula C12H22F6N6OP2, molecular weight 442.28 g/mol. The IUPAC name is benzotriazol-1-yloxy-tris(dimethylamino)phosphanium hexafluorophosphate. Alternative names: Castros reagent and BOP.

The material typically appears as a white to light tan to tan powder. Literature values give a melting point of above 130 °C (dec.). Store it at 2–8 °C, in a tightly closed container. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

It is commonly used for organic synthesis, catalysis and protein and peptide research. Typical end-use sectors are pharmaceutical manufacturing, academic and industrial research and agrochemical production.

Standard pack sizes are 5 g, 25 g, 100 g and 1 kg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
