2-Chloro-4,6-dimethoxy-1,3,5-triazine is used as a peptide coupling agent for the purification of peptides. It is used in the synthesis of 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride through coupling with N-methylmorpholine in tetrahydrofuran. Further, it plays an important role in the production of bis(4,6-dimethoxy-1,3,5-triazin-2-yl) ether, through reaction with 2-hydroxy-4,6-dimethoxy-1,3,5-triazine. In addition to this, it is involved in the preparation of 2-(4,6-dimethoxy-1,3,5-triazinyl)trialkylammonium salts through reaction with various tertiary amines.
