Chemical Properties |
It is colorless needle crystal or amorphous powder. The melting point is 360 ℃ (decomposition). It is easily soluble in acid and alkali, slightly soluble in alcohol, ether, but insoluble in water. The above information is edited by the chemicalbook of Dai Xiongfeng. |
Application |
It can be used for biochemical studies. It can be used as the intermediates of the antiviral drugs acyclovir. It can be used as the intermediate of thioguanine and open-ringed guanine. |
Production method | 5-amino-4-imidazolyl amide can have esterification reaction with isothiocyanate methylbenzene to generate ester, and then successfully reacted with methyl iodide, ammonia to synthesize it. |
Chemical Properties | white to light yellow crystal powder |
Usage | Guanine is on one of the five nucleobases incorporated into biological nucleic acids. Guanine, along with adenine and cytosine, is present in both DNA and RNA, whereas thymine is usually seen only in DNA, and uracil only in RNA. |
