Coupling and water removal are synthesis tools that stand at the cutting edge of high purity and cost-effective manufacture of amides and esters. Leading this technology is T3P®, an exceptional reagent for amide/peptide bond formation. The application of this reagent extends to other condensation reactions, such as esterification, and as a mild reagent for alcohol oxidation and the Lossen rearrangement.
T3P® provides excellent selectivity and high yields with simple product isolation by liquid/liquid extraction. Its advantages translate into high-quality products and improved economics, particularly for large-scale, complex coupling reactions.
The advantages of T3P® include:
- Safe handling: No CMR properties, nontoxic, no allergenic or sensitizing properties
 - Wide range of other condensation reactions possible
 - Several pharma applications up to 100-ton scale
 - Reduced overall process costs
 - Easy purification and workup
 - Low epimerization during coupling
 - No additives required
 - Standard peptide couplings can be done in many different solvents and with common protecting groups
 - Broad functional group tolerance, mild reaction conditions and high yields
