  1. SiliaBond® Propylsulfonic Acid (SCX-2)

    SiliaBond® Propylsulfonic Acid (SCX-2)

    Supported sulfonic acids such as SiliaBond® Propylsulfonic Acid (SiliaBond SCX-2) are in a class of strong acids widely used in different fields of synthetic organic chemistry. Their applications are well known and are used in a large number of settings going from drug discovery laboratories up to manufacturing processes. Among these applications, we denote their uses as acid catalysts, stationary phases for ion chromatography and basic impurity scavengers. Meanwhile, the most common use is probably as a strong cation exchanger (SCX) for the amine “Catch and Release” purification technique in SPE cartridges.

  3. SiliaBond® Tosic Acid nec (SCX)

    SiliaBond® Tosic Acid nec (SCX)

    SiliaBond® Tosic Acid (SiliaBond SCX, Si-TsOH) is a versatile bound strong acid with a pka <<1. It is widely used for the scavenging of amines and other basic functionalities, including weakly basic anilines, borohydrides, and metals such as Ni and Ag. It can also be used as an acid catalyst for organic reactions.Si-TsOH can serve as an alternative method to quench reactions instead of aqueous or organic soluble acids.
