DIPSO 98% Biochemical Grade
Synonym(s): 3-(N,N-Bis[2-hydroxyethyl]amino)-2-hydroxypropanesulfonic acid, N,N-Bis(2-hydroxyethyl)-3-amino-2-hydroxypropanesulfonic acid
Description
DIPSO (3-[N,N-Bis(2-hydroxyethyl)amino]-2-hydroxy-1-propanesulfonic acid) is a high-purity zwitterionic buffering agent widely used in biochemical and molecular biology workflows. With excellent solubility, low UV absorbance, and minimal metal ion contamination, DIPSO provides stable buffering capacity in the near-neutral pH range. Its biochemical-grade specifications make it suitable for protein purification, enzyme assays, cell-free systems, and other sensitive laboratory applications requiring high-performance buffering.
