Loading… Details
SiliaBond® Carboxylic Acid (Si-CAA) can be used as a scavenger for amines or carbonates, and for the quench of alkoxides and organometallic reagents.
SiliaBond Carboxylic Acid is primarily used as a weak cation exchanger (WCX) in solid phase extraction (SPE) and in HPLC. It is preferred over SiliaBond Tosic Acid (SCX) when performing “Catch and Release” purification technique of compounds bearing a permanent positive charge such as tetraalkylammoniums. Using the SCX in this case could make the release of the compound of interest difficult, not to say irreversible, due to the strong interaction between the two strong ioins. SiliaBond Carboxylic Acid has a pka of ≈4.5. It can also be used in ion exchange chromatography (IEC) and has a different selectivity than SiliaBond Tosic Acid (SCX).1,2

Details
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.
SiliCycle offers SiliaBond Propylsulfonic Acid (SCX-2) and SiliaBond Tosic Acid (SCX). Both are considered strong cation exchanger as they maintain a negative charge throughout the pH scale. The aromatic ring of the SiliaBond Tosic Acid makes it slightly more acidic than the other. However, tests have demonstrated that they both have comparable strength. The difference between the two products is mainly in the selectivity. SiliaBond SCX-2 presents a slightly more non-polar character than the SiliaBond SCX, thus reducing secondary non-polar interactions with compounds.

Details
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.
Metals Removed
- Best scavenger for: Rh & Sn
- Good scavenger for: Ag, Cu, Ni, Pd, Pt, Ru & Zn
SiliaBond Tosic Acid has been optimized for use in organic applications. It will not dissolve in methanol or any other solvents. It delivers much higher recovery and has better flow characteristics than corresponding polymer.
The main application of SiliaBond Tosic Acid is as a strong cation exchanger (SCX) in “Catch and Release” purification of amines. It is also widely used as stationary phase in ion exchange chromatography (IEC). Please see SiliaBond Propylsulfonic Acid (SCX-2) for more information.
