Guanine is an organic base widely found in the kingdom of plants and animals. Chemical name is 2-amino-6-oxypurine, colorless square crystal or crystalline powder, in the presence of a large amount of excess amm/onia in an aqueous solution, slowly steam water to obtain small rhomboid crystal, melting point 360ºC(decomposition and partial sublimation). Soluble in amm/onia, caustic /soda and dilute mineral acid, slightly soluble in ethanol, ether, insoluble in water, strong absorption of ultraviolet light, guanosine and guanosine acid components. Its hydrochloride is a monohydrate powder crystal, losing water at 100ºC, losing hydrogen chloride at 200ºC, soluble in acidified water, insoluble in water, ethanol, ether. Guanine can be obtained by hydrolyzing fish scales with hydrochloric / acid. As an important base of nucleic acid, it is one of the four major bases in DNA and RNA, and also a component of various guanosine acids. Its N9 is connected to ribose or deoxyribose C1 by β -glycosidic bond to form guanosine or deoxyguanosine.
