  1. SiliaBond Amine (WAX) (R52030B)

    SiliaBond Amine (WAX) (R52030B)

    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.
  2. SiliaBond Amine (WAX) nec (R52130B)

    SiliaBond Amine (WAX) nec (R52130B)

    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.
  3. SiliaBond Carbonate (CO3) (R66030B)

    SiliaBond Carbonate (CO3) (R66030B)

    SiliaBond Carbonate (Si-CO3) is the silica bound equivalent of tetramethyl ammonium carbonate. It can be used as a general base to quench a reaction, to free base amines in their ammonium salt form and to scavenge acids and acidic phenols, including HOBt, which is widely used in amide coupling reactions.
  4. SiliaMetS Diamine (R49030B)

    SiliaMetS Diamine (R49030B)

    SiliaMetS is a proven scavenger for metals and electrophiles. It scavenges acids, acid chlorides, anhydrides, aldehydes, isocyanates, and chloroformates. Best metal scavenger for: Cr, Pd, Pt, W & Zn. Good scavenger for: Cd, Co, Cu, Fe, Hg, Ni, Pb, Ru, Sc, Se & V.
  5. SiliaBond Dimethylamine (DMA) (R45030B)

    SiliaBond Dimethylamine (DMA) (R45030B)

    SiliaBond Dimethylamine is a silica bound tertiary amine base that can be used in most applications requiring a tertiary amine, particularly as a HCl sponge. Silica bound ammonium salt by-products are easily separated by filtration. This dimethylamine immobilized on silica gel can be used as a base catalyst in Michael or Knoevenagel reactions. It can also be used as a catalyst for alkane oxidation.
  6. SiliaBond DMAP (R75630B)

    SiliaBond DMAP (R75630B)

    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.
  7. SiliaMetS Imidazole (IMI) (R79230B)

    SiliaMetS Imidazole (IMI) (R79230B)

    SiliaMetS Imidazole (Si-IMI) is a versatile metal scavenger for a variety of metals under a wide range of conditions and the preferred metal scavenger for iron catalysts. Best scavenger for: Cd, Co, Cu, Fe, Ir, Li, Mg, Ni, Os, W & Zn. Good scavenger for: Cr, Pd & Rh. It can also be used as an amine base in systems that are generally sensitive to basic conditions compared to other SiliaMetS supported bases.
  8. SiliaBond Guanidine (GUA) (R68230B)

    SiliaBond Guanidine (GUA) (R68230B)

    SiliaBond Guanidine is a silica-supported diisopropylguanidine ligand. It is a very powerful scavenger for the chelating of organic acids in general, especially boronic acids and phenolic acids. It may also be used as a very strong base. It is sufficiently basic to deprotonate moderately acidic hydrogens, as in the alkylation of amines and phenols (Williamson ether synthesis) and the esterification of carboxylic acids using alkyl halides.
  9. SiliaBond Piperazine (R60030B)

    SiliaBond Piperazine (PPZ) (R60030B)

    SiliaBond Piperazine (Si-PPZ) is a useful deprotecting and scavenging agent for Fmoc and Bsmoc amino protecting groups and as a solid-phase Knoevenagel catalyst. According to the results of a study, Si-PPZ is superior to its polystyrene-based equivalent. SiliaBond Piperazine may also be used to scavenge electrophiles.
  10. SiliaBond Piperidine (PIP) (R71530B)

    SiliaBond Piperidine (PIP) (R71530B)

    SiliaBond Piperidine (Si-PIP) is a general purpose tertiary amine base to scavenge acids, thereby avoiding salt elimination problems. Also used as a base catalyst for Knoevenagel condensation.
  11. SiliaBond TMA Acetate (SAX-2) nec (R66430B)

    SiliaBond TMA Acetate (SAX-2) nec (R66430B)

    Strong anion exchangers (SAX) have been widely used in both chromatography and ion exchange SPE to selectively bind acidic drugs and/or analytes. In particular, weakly acidic compounds can be effectively extracted as those types of sorbents retain a permanent positive charge across the pH range. Most commercially available silica-based SAX sorbents are produced with a high selectivity chloride counter ion which reduced retention of acidic drugs when compared with lower selectivity counter ions such as acetate.
  12. SiliaMetS Triamine metal scavenger (R48030B)

    SiliaMetS Triamine (R48030B)

    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.
  13. SiliaBond Triethylamine (WAX-2) (R76530B)

    SiliaBond Triethylamine (WAX-2) (R76530B)

    SiliaBond Triethylamine (SiliaBond WAX-2) is a silica bound tertiary amine base and can be used in most applications requiring a tertiary amine, particularly as a HCl sponge. SiliaBond Triethylamine is also used as weak anion exchanger (WAX) in SPE.
