COMU

CAS: 1075198-30-9

A safe and highly efficient coupling reagent requiring only one equivalent of base during bond formation as it liberates morpholine. This helps to minimize concomitant racemization. Non-allergenic. Couplings with COMU can be monitored visually or colorimetrically, the reagent shows excellent solubility in DMF and NMP. COMU is especially suited for microwave-accelerated SPPS.

COMU

CAS: 1075198-30-9

COMU is an uronium salt used as a coupling agent for peptide synthesis and phosphonamidation. COMU is safe, shows coupling effectiveness comparable to HATU, has an outstanding solubility in organic solvents such as DMF, can be conveniently used with just 1 equivalent of base, achieves great racemisation suppression and is compatible with microwave heating conditions. Additionally, its by-products are water-soluble which denotes ease of purification by extraction. A coupling reaction with COMU can be visually monitored showing colour change at its completion. The high reactivity of the dimethylmorpholino core together with the remarkable leaving group ability of the Oxyma moiety confer to COMU enhanced reactivity compared to benzotriazole-based analogues.
