Chemical Structure
HEPPSO
- CAS No.: 68399-78-0
- Formula:C9H20N2O5S
- Molecular Weight:268.33
IUPAC Name: 2-hydroxy-3-(4-(2-hydroxyethyl)piperazin-1-yl)propane-1-sulfonic acid
InChIKey: GIZQLVPDAOBAFN-UHFFFAOYSA-N
SMILES: O=S(CC(O)CN1CCN(CCO)CC1)(O)=O
Biological Activity: 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 Cu2+ 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 Cu2+ has a very low Ka; therefore, HEPPSO may interfere with studies on copper speciation analysis in natural water bodies[1][2].
