(1-Cyano-2-ethoxy-2-oxoethylidenaminooxy)dimethylamino-morpholinocarbenium hexafluorophosphate (COMU) (CAS: 1075198-30-9) is a third-generation, highly efficient coupling reagent extensively utilized in advanced peptide synthesis. Based on the Oxyma scaffold, this premium uronium salt offers superior coupling performance comparable to HATU, while operating as a significantly safer, non-explosive alternative. It effectively minimizes racemization and ensures exceptionally high yields in amide bond formations. Manufactured under rigorous quality control, our industrial-grade COMU provides outstanding batch-to-batch consistency and high solubility, making it an indispensable intermediate for sophisticated active pharmaceutical ingredient (API) development.
