ON 4-(OR 5-) AMINOGLYOXALINE (IMINAZOLE)

Abstract

The dihydrochloride and sesquipicrate salts of 4-(or 5-)aminoglyoxaline have been prepared in the pure state for the first time. Previous attempts to isolate the substance have failed largely because insufficient allowance was made for the instability of the substance in aqueous media. The new glyoxaline is highly reactive and has unusual properties for a glyoxaline. It has certain properties like those of 4-(or 5-)guanidinoglyoxaline, being here proved to be a hydrolysis product of guanine.
