Chemische Eigenschaften
It is a pale yellow crystal with relatively stable chemical properties that do not cause decomposition at room temperature. Its structure includes nitrogen heterocycles, which give rise to remarkable alkalinity and the formation of volatile acid salts. It is soluble in dimethyl sulfoxide, but has only slight solubility in water.
Verwenden
6-Chloropurine is used in the preparation of 9-alkylpurines through alkylation with various substituted alkyl halides in dimethyl sulfoxide. It is also used to prepare 6-succinoaminopurine.
synthetische
6-chloropurine is synthesized by reacting hypoxanthine with phosphoryl chloride in the presence of an unreactive base such as dimethyl aniline. It may likewise be formed by heating hypoxanthine under pressure with phosphoryl chloride as well as with a reagent prepared by adding water, preferably about by volume, to dry phosphoryl chloride.

Definition
ChEBI: 6-Chloro-1H-purine is a member of purines. It is metabolized to form 6-mercaptopurine and has been used as an antineoplastic.
Allgemeine Beschreibung
