Details

SiliaBond® Amine (Si-NH2) is an effective scavenger of acid chlorides, sulfonyl chlorides, isocyanates and other electrophiles. Researchers compared PS-Triamine to SiliaBond Amine for the removal of acid chlorides in the synthesis of 2,9-disubstituted guaninies. Using SiliaBond Amine to remove excess acid chloride gave higher yields and better purity in more than 93% compared to PS-Trisamine. For complete details, please refer to the scavenger case study.1

SiliaBond Amine eliminates tedious post reaction purification. It scavenges faster, is easier to add and filter, and can be used in any solvent. Si-NH2 has been shown to be effective metal scavenger2 and catalyst for Knoevenagel reactions.3, 4  It has also been used as support in solid-phase chemistry for peptide synthesis followed by enzymatic hydrolysis5 and for Claisen rearrangement.6

Metals Removed

  • Best scavenger for: Cd, Cr, Pd & Rh.
  • Good scavenger for: Co, Cu, Fe, Hg, Pb, W & Zn.

SiliaBond Amine is also used in chromatography as normal phase sorbent. It is used in the preparation of peptides, drugs and metabolites from physiological fluids and for the separation of mono- and polysaccharides.  Si-NH2 is more retentive towards basic compounds. When used at pH ≤ 7.8, it is protonated and may be used as a weak anion exchanger (WAX). SiliaBond Amine has been used for the solid-phase extraction of sugars,7 for the separation of steroids,8 cholesterol, and triglycerides,9 and in size exclusion chromatography of cationic polymers.10  Si-NH2 is also available non-endcapped (R52130B) for additional retention of polar and cationic compounds.

Details

SiliaBond® Diol (Si-Diol) may be used as boronic acid scavenger in the same way as PS-DEAM.

SiliaBond Diol may also be used as polar sorbent in normal phase and aqueous size exclustion chromatography. Like bare silica, SiliaBond Diol has the ability to form hydrogen bonds and the capacity to separate structural isomers. Since most of its surface is covered with organic functions, the SiliaBond Diol absorbs less water, which leads to a more reproducible activity. It is also the sorbent of choice when working in normal phase in the presence of water. It has a different selectivity than bare silica gel and slight modifications in the composition of the solvent mixture may be necessary to obtain similar retention. In SPE, it is used for the isolation of drugs and metabolites from physiological fluids.

Details

SiliaBond® Fluorochrom (Si-FCM) is a fluorinated sorbent particularly useful for the separation of fluorine containing molecules from non-fluorous ones. This technique is slowly gaining acceptance in the scientific community mostly for applications in SPE and HPLC. The applications of these types of sorbent are not limited to fluorous compounds but may also be used in chromatographic separation of non-fluorinated molecules, just like a regular reversed-phase would do, but with different selectivity. SiliaBond Fluorochrom presents the highest level of fluorine available and has a proprietary structure.

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.
