Description

Application

Investigation of the Interaction of Sodium Chloride and Two Amino Sulfonic Acids, HEPES and MOPSO, by EMF Measurements.: This study explores the electrochemical interactions between sodium chloride and the amino sulfonic acids HEPES and MOPSO, providing insights into their behavior in solution which may be relevant for biochemical applications (Wu et al., 1991).

Disclaimer

According to Ferreira, et al., MOPSO can have a strong interaction with iron in solution. Based on this citation, it is recommended to use plastic-coated or PTFE-coated utensils when working with this chemical.
