CAS NO.1839-18-5 2-Chloroadenine

2-Chloroadenine (CAS: 1839-18-5, Synonyms: (2-CHLOROADENINE;2-CHLORO-6-AMINOPURINE;6-Amino-2-chloro-7H-purine;Cladribine EP Impurity C;Regadenoson impurity H;2-Chlorophenthiazine;2-chloroadenine(2-cl-ade);CHLOROADENINE) is an important purine derivative with a chlorine atom at the 2-position and an amino group at the 6-position of the purine ring. This specific structure makes it a key building block for the preparation of modified nucleosides and nucleoside analogs in medicinal chemistry and biochemical synthesis. It is widely used in the design and synthesis of lead compounds for antiviral drugs (such as nucleoside reverse transcriptase inhibitors) and antitumor agents (e.g., purine analog chemotherapeutics), as well as in the development of bioactive molecules with immunomodulatory or enzyme inhibitory activity. The compound typically exists as a solid, is sensitive to moisture and light, and should be stored under cool, dry conditions.
