Bond Elut PRS (propyl sulfonic acid) is a strong cation-exchange sorbent that is also relatively high in polarity. With no appreciable degree of hydrophobicity, in nonpolar solvents, PRS is capable of polar and hydrogen bonding interactions. Due to the very low pKa of PRS, it is recommended for weaker cationic species, such as pyridinium compounds.
