Application:
Together with hydroxy chemical compound, glyoxal can produce acetal, used as raw material of glyoxylic acid, M2D resin, imidazole and some other products. In recent years, glyoxal's application is wider and wider. In pharm. Industry, glyoxal is mainly used in medicine such as imidazole series. In intermediates industry, glyoxal is used as the material of acetaldehyde acid, allantoin and berberine, etc.
