-
SiliaBond® Amine nec
SiliaBond® Amine (Si-NH2) is an effective scavenger of acid chlorides, sulfonyl chlorides, isocyanates and other electrophiles. Si-NH2 has been shown to be effective metal scavenger and catalyst for Knoevenagel reactions. SiliaBond Amine is also used in chromatography as normal phase sorbent.
-
SiliaBond® Piperazine
SiliaBond® Piperazine (Si-PPZ) is a useful deprotecting and scavenging agent for Fmoc1 and Bsmoc2 amino protecting groups and as a solid-phase Knoevenagel catalyst. According to the results of a study1, Si-PPZ is superior to its polystyrene-based equivalent. SiliaBond Piperazine may also be used to scavenge electrophiles.
-
SiliaBond® Tosyl Hydrazine
SiliaBond® Tosyl Hydrazine (Si-TsNHNH2) is an effective scavenger of carbonyl compounds. It has been used to selectively remove aldehydes in the presence of ketones since the scavenging of ketones requires an acid catalyst. Once bound, sulfonyl hydrazones can be utilized in other synthetic transformations.
-
SiliaBond® DMAP
SiliaBond® DMAP (Si-DMAP) is the supported equivalent of 4-dimethylaminopyridine commonly used as a nucleophilic catalyst in a wide variety of reactions such as acylation, amidation or acetylation.
-
SiliaMetS® Triamine
SiliaMetS® Triamine (SiliaMetS WAX-3, Si-TRI) is effective for scavenging metals such as Pb, Co, Ru and Pd. Our screening studies have shown it to be the preferred scavenger for Pb. It can also be used as a scavenger for acid chlorides, isocyanates and other electrophiles.
-
SiliaMetS® Diamine
SiliaMetS® Diamine (Si-DIA) is a proven scavenger for metals and electrophiles. It scavenges acids, acid chlorides, anhydrides, aldehydes, isocyanates, and chloroformates as well as Pb, Ni, and Cd.
-
SiliaBond® Amine
SiliaBond® Amine (Si-NH2) is an effective scavenger of acid chlorides, sulfonyl chlorides, isocyanates and other electrophiles. Si-NH2 has been shown to be effective metal scavenger and catalyst for Knoevenagel reactions. SiliaBond Amine is also used in chromatography as normal phase sorbent.

SiliaPrep™ SPE Cartridges Amine (WAX)
SiliaPrep Amine is a weak anion exchanger sorbent used in replacement of SAX for strong anions to avoid irreversible retention. Can also be employed as a metal scavenger and norman phase conditions.
-
SiliaPrep™ SPE Cartridges Amine nec (WAX)
SiliaPrep Amine nec is a weak anion exchanger sorbent used in replacement of SAX for strong anions to avoid irreversible retention. Can also be employed as a metal scavenger and norman phase conditions.
-
SiliaPrep™ SPE Cartridges Piperazine (SPE-R60030B)
SiliaPrep Piperazine is a weak anion exchanger that can be used in replacement of SAX and SAX-2 for strong anions to avoid irreversible retention. By using this phase, elution can be done at a lower pH (around pH 8-9) comparatively to the SiliaPrep Amine.
-
SiliaPrep™ SPE Cartridges Diamine
SiliaPrep diamine can be used in replacement of SAX for strong anions to be irreversible retention. Can also be employed as metal scavenger and in normal-phase conditions.
-
SiliaPrep™ SPE Cartridges Diamine nec
SiliaPrep diamine can be used in replacement of SAX for strong anions to be irreversible retention. Can also be employed as metal scavenger and in normal-phase conditions.
-
SiliaPrep™ SPE Cartridges Triamine
SiliaPrep Metal Scavengers will lower the residual metal concentration of various metal complexes to single digit ppm.
-
