HDMC

HDMC is an aminium-type coupling reagent derived from dimethylmorpholino urea. In addition to decreasing the racemization level, the morpholine moiety has a remarkable effect on the stability and reactivity of the reagent.

HDMC is a registered patent of Luxembourg Bio Technologies (No. 101784522/8,524,898).

Applications

  • HDMC used together with OxymaPure® has been used to prepare COMU in situ and therefore to overcome the rather low stability of COMU in solvents such as DMF.
  • HDMC/OxymaPure combination has been found to be the best coupling reagents for Automated Peptide Synthesizer.

Studies

  • Morpholine-Based Immonium and Halogenoamidinium Salts as Coupling Reagents in Peptide Synthesis
