Hopax is a manufacturer and supplier of Pipes (CAS 5625-37-6), a zwitterionic biological buffer often used as a buffering agent in biological and biochemical research.
Similarly to Mes and Mops (also manufactured by Hopax), this Good's Buffer lacks the capability to form a complex with most metal ions, therefore it is recommended for use as a noncoordinating buffer in different solutions with metal ions. Pipes contains two sulfate groups and is capable of exchanging a proton from each group, allowing it to buffer at approximately half the concentration of Hepes.
Its use has been reported in protein purification, chromatography and cosmetics. In personal care and cosmetics application, Pipes functions as a skin desquamation agent and a cream composition.
Hopax's Pipes is specially tested and certified to be free of DNase, RNase and protease activity for molecular biology application.
Synonyms: 1,4-Piperazinediethanesulfonic acid | Piperazine-1,4-bis(2-ethanesulfonic acid) | Piperazine-N,N′-bis(2-ethanesulfonic acid)
