Molecular formula : CAS :
nature : 2-hydroxy Pteridine. From the water to be like crystals (a hydrate), the decomposition of 240 ° C, 120 ° C (13.33Pa) dehydration. From 2-hydroxy-4 ,5-two Pyrimidinamine reaction with glyoxal or 2-chloro-Pteridine hydrolysis Preparation. 4-Hydroxy - Pteridine, melting point> 350 ° C in the water showed fluorescent purple and susceptible to hot acid or alkaline degradation of 2-amino-pyrazine-3-acid amide and its from 4,5-diamino-6-hydroxypyridine glyoxal and the hydrogen sulfite sodium adduct preparation. Its 6-hydroxy Pteridine, melting point> 240 ° C (decomposition), in concentrated hydrochloric acid and hydrogen chloride can be aptly salt crystals and susceptible to hydrogen peroxide oxidation, as 6,7-dihydroxy Pteridine. From 4,5-Diamino with diethyl acetal glyoxal in the semi-aqueous solution from heating system. For synthesis and biochemical research reagents.
