very slightly yellow to cream crystalline powder | [Definition]
A simple nitrogenous organic molecule with a double ring
structure. Members of the purine group include adenine and guanine, which are constituents of the nucleic acids, and certain
plant alkaloids, such as caffeine and theobromine. | [Definition]
ChEBI: The 9H-tautomer of purine. | [Definition]
purine: An organic nitrogenous base(see formula), sparingly soluble inwater, that gives rise to a group ofbiologically important derivatives,notably adenine and guanine,which occur in nucleotides and nucleicacids (DNA and RNA). | [General Description]
Purine is a heterocyclic organic compound constituting a pyrimidine ring fused to an imidazole ring. | [Purification Methods]
It crystallises from toluene or EtOH, and sublimes at 100-150o/0.1mm or 160o/10-4mm. The picrate has m 207-209o after crystallisation from 20volumes of H2O. [Beilstein 26 H 354, 26 III/IV 1736.] |
