Ferris, James P. published an article in 1966, the title of the article was Studies in prebiotic synthesis. I. Aminomalononitrile and 4-amino-5-cyanoimidazole.COA of Formula: C10H11N3O3S And the article contains the following content:
The syntheses of aminomalononitrile and 4-amino-5-cyanoimidazole are described. Acid anhydrides react with aminomalononitrile to yield oxazoles. Aminomalononitrile is converted to diaminomaleonitrile by cyanide and to 4-amino-5-cyanoimidazole by formamidine. Adenine results from the reaction of 4-amino-5-cyanoimidazole with formamidine. 4-Cyano-5-aminooxazole is converted to 7-aminooxazolo[5,4-d]pyrimidine on treatment with formamidine. 16 references. The experimental process involved the reaction of 2-Aminomalononitrile 4-methylbenzenesulfonate(cas: 5098-14-6).COA of Formula: C10H11N3O3S
2-Aminomalononitrile 4-methylbenzenesulfonate(cas:5098-14-6) belongs to nitriles. Some nitriles are manufactured by heating carboxylic acids with ammonia in the presence of catalysts. This process is used to make nitriles from natural fats and oils, the products being used as softening agents in synthetic rubbers, plastics, and textiles and for making amines.COA of Formula: C10H11N3O3S
