Abstract: HILIC method was established to separate and analyze highly polar compound methacryloyloxyethyl trimethyl ammonium chloride (DMC) and its impurities. Using two different chromatographic columns:HP-Cyano column and X-Bridge HILIC column,highly polar compound DMC and its impurities were all well separated by gradient elution using acetonitrile and water as mobile phase. With the two different chromatographic columns, four impurities in DMC were separated, such as dimethylaminoethyl methacrylate (DM),methacrylic acid (MAA), choline chloride (CC) and Hydroquinone monomethyl ether (MQ). This method has higher practical value, which can be used effectively in separated highly polar compounds.

Key words: hydrophilic interaction liquid chromatography (HILIC), methacryloyloxyethyl trimethyl ammonium chloride (DMC), highly polar compounds, separation
