Applications
- T-BEC® carbodiimide surpasses DIC in terms of efficiency, making it a more effective coupling reagent.
- In contrast to DIC, T-BEC® does not generate an oxadiazole side-product when used with OxymaPure, eliminating the formation of HCN.
- T-BEC® urea (TBEU) demonstrates exceptional solubility in commonly employed peptide coupling solvents like DMF or NMP, as well as future green/ binary solvents. This reduces the risk of equipment clogging during manufacturing.
- T-BEC® employs the same coupling protocols as other carbodiimides, ensuring easy integration into existing chemical processes.
- T-BEC® is recognized as a greener coupling reagent, offering environmentally friendly properties and contributing to sustainable chemical practices.
