Purine Chemical Properties,Usage,Production

Chemical Properties

very slightly yellow to cream crystalline powder

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.

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.

Definition

ChEBI: The 9H-tautomer of purine.

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).

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.]
