The resin is characterized by its good rigidity and an exceptionally high loading of COOH groups. This resin is quite unique in its properties as most other carboxylic acid resins are based on base-labile methacrylate resins, whereas Temiz DVB-COOH MP is based on highly stable cross-linked polystyrene base.
Application areas
TEMIZ DVB-COOH for use in separation, batch binding, solid phase synthesis or scavenging. The material is unique in its properties.
- an alternative to strong cation exchangers (SCX) containing sulfonic acid functional groups. The weaker ion exchange functionality (pka ca 4.5) may be advantageous where a more balanced binding strength is desired. Desorption is possible under milder conditions than conventional SCX resins. This allows for a simpler “catch-and-release” purification eg for scavenging amines or carbonates.
- Quenching of alkoxides and organometallic reagents.
- The stable DVB backbone allows for harsher binding and washing conditions than comparable WCX resins based on acrylates or silica.
- A DVB backbone in combination with carboxylic acid functional groups is a unique material on the market and offers a novel selectivity combined with a high chemical robustness for many new applications.
