| | Purine Usage And Synthesis |
| Chemical Properties | very slightly yellow to cream crystalline powder | | Uses | Organic synthesis, metabolism, and biochemi-
cal research.
(2) One of a number of basic compounds found in
living matter and having a purine-type molecular
structure.
| | Uses | Purine can be used human immunogenic epitopes of H,K, and E human endogenous retroviruses. | | Uses | Purine can undergo direct C-H functionalization in the presence of palladium catalyst to form various biologically important products. | | 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 | 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). | | Definition | ChEBI: The 9H-tautomer of purine. | | 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.] |
