HEPPSO is a zwitterionic Good's buffer suitable for physiological pH conditions. HEPPSO forms high-order oligomers in aqueous solutions and can form a 1:1 complex with Cu 2+ via its hydroxyalkyl and tertiary amine groups. However, HEPPSO contains a structurally similar trace impurity lacking an alkanesulfonic acid side chain. The complex formed by this impurity and Cu 2+ has a very low Ka; therefore, HEPPSO may interfere with studies on copper speciation analysis in natural water bodies .
