    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.
  8. 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.
  9. SiliaMetS Imidazole (IMI) (R79230B)

    SiliaMetS Imidazole (IMI) (R79230B)

    SiliaMetS Imidazole (Si-IMI) is a versatile metal scavenger for a variety of metals including Cd, Co, Cu, Fe, Ni, Pd, and Rh under a wide range of conditions and the preferred metal scavenger for iron catalysts. It can also be used as an amine base in systems that are generally sensitive to basic conditions compared to other SiliaMetS supported bases.
  10. 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.
  11. SiliaBond Morpholine (MOR) (R68030B)

    SiliaBond Morpholine (MOR) (R68030B)

    SiliaBond® Morpholine (Si-MOR) is commonly used as an acid sponge. It is used in the same manner as morpholine functionalized polymers.

  15. 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.
  16. SiliaBond TMA Chloride (SAX)

    SiliaBond TMA Chloride (SAX) (R66630B)

    SiliaBond TMA Chloride (SiliaBond SAX, Si-TMACl) is mainly used as strong anion exchanger (SAX) in ion chromatography and ion exchange SPE. The function bears a positive charge across the whole pH range as well as in organic solvents. It is especially used for the “Catch and Release” purification of weak acids.
  17. SiliaBond TMA Chloride (SAX) nec (R66530B)

    SiliaBond TMA Chloride (SAX) nec (R66530B)

    SiliaBond TMA Chloride (SiliaBond SAX, Si-TMACl) is mainly used as strong anion exchanger (SAX) in ion chromatography and ion exchange SPE. The function bears a positive charge across the whole pH range as well as in organic solvents.
