  1. SiliaMetS® Thiol

    SiliaMetS® Thiol

    SiliaMetS® Thiol (Si-Thiol) is a robust metal scavenger for a variety of metals including Pd, Pt, Cu, Ag and Pb under a wide range of conditions. It has been used in pharmaceutical processes up to the pilot plant scale. It is our most versatile metal scavenger and is the preferred metal scavenger for Pd(II), Cu, Ag, and Hg.

  2. SiliaMetS® TAAcOH

    SiliaMetS® TAAcOH

    SiliaMetS® TAAcOH (SiliaMetS Triaminetetraacetic Acid) is a silica bound metal scavenger for Pd(0), Ni(0) and Cu. It is the supported version of EDTA in its free form. It is an effective scavenger for metals in low or zero oxidation states, which includes many of the most synthetically useful catalysts such as tetrakis-(triphenylphosphine)palladium(0).

  3. SiliaMetS® TAAcONa

    SiliaMetS® TAAcONa

    SiliaMetS® TAAcONa or (or SiliaMetS Triaminetetraacetate, sodium salt) is a silica bound metal scavenger for Pd(II), Ni(II) and Cu. It is the supported version of EDTA in its sodium salt form. It is an effective scavenger for metals in higher oxidation state, 2+ or higher.

  4. SiliaMetS® Thiourea

    SiliaMetS® Thiourea

    SiliaMetS® Thiourea (Si-THU) is a versatile metal scavenger for all forms of palladium and is widely used in the pharmaceutical industry. It works particularly well in organic solvents. It can also be used to scavenge Ag, Pt, Ru, Rh and Hg. Once complexed with a transition metal, it has been reported as being an effective catalyst.

  5. SiliaMetS® Dimercaptotriazine (DMT)

    SiliaMetS® Dimercaptotriazine (DMT)

    SiliaMetS® DMT (Si-DMT) is the silica bound equivalent of 2,4,6-trimercaptotriazine (trithiocyanuric acid). It is a versatile metal scavenger for a variety of metals including Cd, Co, Ni, Pd, Pt, Rh, and Ru under a wide range of conditions and the preferred metal scavenger for ruthenium catalysts.

    TMT has been reported to efficiently remove palladium and heavy metals by precipitation. Unfortunately, its solubility in organic solvents causes problem. SiliaMetS DMT solves this issue and almost all solvents can now be used.

  6. SiliaMetS® Imidazole

    SiliaMetS® Imidazole

    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.

    SiliaMetS Imidazole can also be used as an amine base in systems that are generally sensitive to basic conditions compared to other SiliaMetS supported bases.

  7. SiliaMetS® Cysteine

    SiliaMetS® Cysteine

    SiliaMetS® Cysteine (Si-Cys) is the silica bound equivalent of the amino acid Cysteine. By attaching the molecule to the backbone via the amino group, the thiol group remains free and accessible for higher metal scavenging efficiency. It is a versatile metal scavenger for a variety of metals including Pd, Sn, Ru, Pt, Cu, Rh, Cd and Sc under a wide range of conditions and the preferred metal scavenger for tin residues.

  8. SiliaBond® Potassium Permanganate nec

    SiliaBond® Potassium Permanganate nec

    Potassium permanganate is a strong oxidant that will oxidize methyl groups and alcohols to carboxylic acids. SiliaBond® Potassium Permanganate (Si-KMnO4) increases recoveries, facilitates work-up, and expands the scope of the chemistry because it can be used in all organic solvents eliminating solubility issues. With SiliaBond Potassium Permanganate, the manganese salt by-products stays adsorbed onto the silica.

  9. SiliaBond® Silver Nitrate (AgNO3) nec

    SiliaBond® Silver Nitrate (AgNO3) nec

    Chromatography with silver nitrate is a well known and established methodology for the separation of non polar compounds with similar polarities. Generally, with a mixture of unsaturated compounds such as alkenes, lipids, steroids, terpenes, etc, standard separation procedures lack in efficiency. However, by using SiliaBond® Silver Nitrate for your column chromatography along with SiliaPlate™ Ag for your TLC, you will have the necessary tools to circumvent the problem.

  10. SiliaBond® Pyridinium Chlorochromate nec (PCC)

    SiliaBond® Pyridinium Chlorochromate nec (PCC)

    SiliaBond® Pyridinium Chlorochromate (Si-PCC) is used for the general oxidation of alcohols to carbonyl compounds, selective oxidation of allylic and benzylic alcohols, organometallic oxidation, oxidative transpositions, oxidative cleavages, allylic and benzylic oxidation and oxidative cyclizations.

Testimonials

“The high quality nature of the columns and plates from SiliCycle has allowed us to achieve a level of reproducibility with our compound libraries that would be unheard of with any other production line.”
[Steven Marois, Boston University CMLD]

“Several of my teams have successfully employed SiliCycle resins to scavenge metals from APIs. The fact that these scavengers work so well allow us to employ Pd-catalyzed cross couplings as final steps in API synthetic sequences confidently, knowing that we will likely be able to reduce transition metal contamination to acceptable levels in the final drug substance.”
[Akin Davulcu, Bristol-Myers Squibb]

“BioVectra has been able to leverage its large scale chromatography capability with the technical and product capability of the SiliCyle team into the manufacturing of important oncology active pharma ingredients. We have been associated with SiliCycle since 1998, and look forward to working together on many new projects in the future.”
[Dale Zajicek, BioVectra]
