Recent publication: use of Sabit DVB-TBD in catalytic reactions

SABIT DVB-TBD is a potential game changer for users of organocatalyst superbases such as DBU or TBD. This new product features Triazabicylcodecene firmly immobilized on a rigid and higly porous solid carrier. It is an alternative to polymer supported bases such as PS-TBD Triazabicyclodecene -polystyrene resin bound products with only 1 or 2 % DVB. Sabit DVB-TBD with 50 % DVB has many new advantages, it can be used

in virtually any solvent
in flow systems
in repeated use

Successful use of Sabit DVB-TBD to catalyze the formation of trichloroacetimidates from alcohol and trichloroacetonitrile. Work conducted by Prof. Christian Pedersen at University of Copenhagen, Denmark.

Results: using this new rigid resin with bound TBD led to efficient catalysis of the reaction with high % of conversion to product, without cumbersome product and catalyst separation. Read the full story with all details in our recent open access publication in Chemistry Methods 2026.

Fully Hydrophilic SPPS Resins: SABIT PDMA AE LR

Discover a new standard in solid-phase peptide synthesis. For years, chemists have been limited to conventional hydrophobic polystyrene (PS) resins and partially polar PS-PEG composites. Today, we introduce a powerful addition to your synthesis toolkit: our new, fully hydrophilic poly-dimethylacrylamide aminoethyl (AE) resin beads, engineered with low rigidity (LR) = high swelling specifically for advanced SPPS workflows.

Featuring a 100% amide-based backbone, this novel architecture is engineered to directly solve the modern challenges plaguing the peptide industry—effectively eliminating sequence aggregation and overcoming the structural limitations of synthesizing long, complex, or difficult peptides.

Key Features:

- 100% Amide Backbone: Emulates the peptide environment to repel growing chains and prevent folding or interchain aggregation.
- Upgraded Resin Integrity: Eliminates the fragility of historic PDMA variants; maintains low backpressure and bead integrity under continuous flow.
- Precise 0.5 mmol/g Loading: Verified via quantitative titration to ensure accurate reagent dosing and optimized process economics.
- 100% Swedish Manufacturing: Developed and produced entirely from scratch in our Lund facilities for absolute reproducibility and scaling control.

Rigid Resins (RR) that retain their porosity and capacity in all solvents

Make the best out of our new rigid resin collection to achieve novel selectivities in separation and adsorption.

We are the only provider of this rigid resin type of products, where the resins retain their porosity and accessible surface even in organic solvents, oils and other non-aqueous solutions. This means, high capacity also in solvents or mixture of solutions where conventional resins collapse and lose their accessible surface area.

These new resin types enable purifications so far not possible with current conventional resins.
