Biotage^® PS-Carbodiimide

Coupling Agent for Amide and Ester Synthesis, Formation of Pentafluorophenyl (PFP) and Other Activated Esters

Biotage® PS-Carbodiimide is a neutral, bound carbodiimide that can be used for the synthesis of amides and esters. In general, PS-Carbodiimide was found to synthesize amides in high yield and purity without evidence of residual amine or carboxylic acid. Unreacted carboxylic acid, normally used in excess relative to the amine, remains bound to the resin during workup.

Benefits

For over 15 years Biotage has been guiding and leading the industry in supported reagents and scavengers. PS-Carbodiimide is very stable and lost less than 5% of its initial activity when stored at 4 ˚C for 2 years. This is due to increased stabilization provided by the ether linkage. Unlike inferior copies, the carbodiimide moiety in Biotage PS-Carbodiimide is not Benzylic by design.

Efficiently deliver chemistry

More effective than traditional methods, polymer supported chemistry has been used widely in applications for over fifty years. Biotage supported reagents and scavengers are based on functionalized polystyrene or silica polymers and are 100% insoluble, therefore can be added to reactions and completely removed afterwards.

Robust, reliable, scalable and safe

From grams in research through to multi kilogram quantities in production campaigns. In general, PS-Carbodiimide was found to synthesize amides in high yield and purity without evidence of residual amine or carboxylic acid. Unreacted carboxylic acid, normally used in excess relative to the amine, remains bound to the resin during workup.
