Adenine hemisulfate (Diadenine sulphate) is a sulfate salt form of adenine which is a purine derivative and a nucleobase with a variety of roles in biochemistry.

Adenine (6-Aminopurine), a purine derivative, is a nucleobase with various roles in biochemistry including cellular respiration, in the form of both the energy-rich ATP and NAD and FAD, and protein synthesis, as a chemical component of DNA and RNA.

Adenine monohydrochloride hemihydrate is a high affinity adenine receptor agonist (Ki = 18 nM at rat adenine receptor). It inhibits forskolin-stimulated cAMP formation in CHO cells transfected with the adenine receptor and also stimulates GTPγS binding (pEC50 values are 8.54 and 7.21 respectively).

Adenine hydrochloride (6-Aminopurine hydrochloride) is a hydrochloride salt form of adenine which is a nucleobase with a variety of roles in biochemistry.
