Product Name:Piperazine-N,N'-bis(2-ethanesulfonic acid) sesquisodium salt
English Name:Piperazine-N,N'-bis(2-ethanesulfonic acid) sesquisodium salt
CAS No.:100037-69-2
Aliases:PIPES sesquisodium salt, 1,4-Piperazinediethanesulfonic acid sesquisodium salt, Piperazine-1,4-bis(2-ethanesulfonic acid) hemisodium salt
Molecular Formula:C16H33N4Na3O12S4
Physical Properties:White crystalline powder, readily soluble in water, with a nearly neutral aqueous solution (pH approximately 6-7). As a zwitterionic buffer, its pKa is about 6.8 at 25°C, giving an effective buffering range of pH 6.1-7.5. Insoluble in organic solvents such as ethanol and diethyl ether, and exhibits good thermal stability.
Uses:Primarily used for preparing buffer solutions in biochemical and molecular biology research, including cell culture, protein and nucleic acid separation. It maintains a stable pH environment with negligible metal ion binding, thus minimizing interference with enzymatic reactions.
Technical Specifications:
Assay (titrimetric) ≥99.0%
pH (1% aqueous solution, 25°C) 6.5-7.5
Loss on drying ≤0.5%
Heavy metals (as Pb) ≤10 ppm
Solubility test: 10% aqueous solution is clear and transparent
