The resin chemistry backbone consists of highly stable DVB-Styrene with polar, weakly basic pyridine groups.
Other providers of cross-linked pyridine resins have low rigidity, with lower levels of cross-linkage. Temiz Polar RR resins have exceptionally high levels of cross-linkage that provide the highest level of resin rigidity on the market.
The flat aromatic structure of pyridine allows for pi-pi interactions with other aromatic compounds.
Weakly basic pyridine group can also act as resin-bound catalyst instead of eg pyridine in solution.
Resin bound pyridine can scavenge strong acids, metals, and other ionic species via ion-exchange mechanisms.

The large particles are optimal for preparative applications for both in adsorption in suspension or chromatographic processes.
