SiliaMetS Triamine (R48030B)   Loading…  

Details

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.

Metals removed

  • Best scavenger for: Cr, Pd, Pt. W & Zn
  • Good scavenger for: Ag, Cd, Co, Cu, Fe, Hg, Ni, Os, Pb, Rh, Ru & Sc

SiliaMetS Triamine may also be used as a weak anion exchanger (WAX) in the same way as SiliaMetS Amine and SiliaMetS Diethylamine, and is the closest silica equivalent of polyethyleneimine commonly used on the market.

SiliaBond Amine (WAX) (R52030B)   Loading…  

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.

SiliaBond Carbamate (CAR) (R50130B)   Loading…  

Details

SiliaBond® Carbamate (CAR) is a versatile scavenger for nucleophiles. It readily scavenges amines, thiols, thiolates, alcohols, alkoxides, and acidic phenols. Loading is determined by the removal of benzylamine in hexane at room temperature.

Si-CAR has been used to scavenge amines in a “cap-tag” methodology for oligosaccharide preparation by automated solid phase synthesis1 and in the preparation of 2,5-diketopiperazines and 1,4-benzodiazepine-2,5-diones.2

Silica supported Carbamate has superior reactivity in a broader range of solvents when compared to polymer-based materials.

SiliaBond Carbodiimide (DCC) (R70530B)   Loading…  

Details

SiliaBond® Carbodiimide (Si-DCC) is a bound neutral carbodiimide that may be used for the synthesis of amides, esters, and activated esters. Loading is determined by titration of the excess oxalic acid after formation of oxalic anhydride. The use of silica-supported DCC eliminates purification issues caused by the formation of DCU as it remains bound to the silica.

 

Applications and uses of SiliaBond Carbodiimide are not restricted to standard amides. As a matter of fact, it has been successfully used for the synthesis of Weinreb amides and acylsulfonamides.
