Supported sulfonic acids are a class of strong acids (pKa < 1) widely used in different fields of synthetic organic chemistry. Their most common use is probably as strong cation exchangers (SCX) for the “Catch and Release” purification of amines in SPE cartridges, which will be further discussed in this Application Note.
