The color reaction product of creatinine with potassium 1,2-naphthoquinone-4-sulfonate was isolated as dark blue violet prisms with mp 318℃. This compound has the characteristic that its alkaline solution is very unstable to the oxygen gas to decolarize. An equimolar amount of oxygen to the color reaction product dissolved in aqueous sodium hydroxide solution was absorbed and a decomposition product, 2-hydroxy-1,4-naphtho-quinone, was formed. This compound also produced the same product in a strong acidic solution. The structure of the color reaction product was elucidated to be 4-[3'H-1'-methyl-2'-imino-4'-oxo-5'-imidazo-lylidene]-1-oxo-2-hydroxy-naphthalene on the basis of its spectral properties.
