产品介绍
Product description
White crystal or powder, is a low-toxicity biologically inert amino alcohol, soluble in ethanol and water, slightly soluble in ethyl acetate, benzene, insoluble in ether, carbon tetrachloride.The aqueous solution does not absorb carbon dioxide in the air, and the pH of the 0.1 mol/L aqueous solution is 10.4.It has corrosive effects on copper and aluminum, and can buffer carbon dioxide and acid in vivo and in vitro. It is an effective amine compound that controls the pH value within the physiological range.
Main purpose
Biological buffer, buffer range pH7.0～9.0.Acid gas absorber.The reference substance of acid titration method.Determination of mercapto groups in proteins by electric current titration.Separation of serum protein by electrophoresis on paper.Starch plate electrophoresis separates toxins.Synthetic surfactants.
