Piperazine-N,N'-bis(2-hydroxypropanesulphonic acid) disodium salt Usage And Synthesis

Chemical Properties

White solid

Uses

POPSO sodium A zwitterionic buffer.

Synthesis

Piperazine-N,N-bis(2-hydroxyethanesulfonic acid) sodium salt (P-2SO3-2Na) was prepared as follows: piperazine (2.15 g, 25 mmol) was dissolved in 20 mLDI water. Then ClCH2CH2SO3Na (9.23 g, 50 mmol) and NaOH (1.60 g, 50 mmol) were added sequentially. The resulting solution was stirred continuously overnight at 40??C. A clear solution was formed. The product was obtained by precipitation from cold ethanol and purified from H2O/EtOH. The white powder piperazine-N,N-bis(2-hydroxyethanesulfonic acid) sodium salt was collected after drying (yield >99%).
