ChEBI: 2-amino-9-[(2R,3R,4S,5R)-3,4-dihydroxy-5-(hydroxymethyl)-2-oxolanyl]-3H-purine-6-thione is a purine nucleoside.

Thioguanosine is crystallised (as hemihydrate) from hot H2O (charcoal) and cooled slowly to give tapered prisms. It also crystallises by dissolving in dilute NH3 and acidifying with acetic acid, and then recrystallising from H2O. UV: (pH 4-6) max at 257nm ( 8,820) and 342nm ( 24,800), and (pH 10.4-12.0) max at 252nm ( 14,700) and 319.5nm ( 21,000). [Fox et al. J Am Chem Soc 80 1667 1958, Beilstein 26 III/IV 3927.]
