Guanosine

Synonyms: Guanine riboside, 9-β-D-Ribofuranosylguanine, Guanine-9-β-D-ribofuranoside, Vernine, 2-Amino-9-β-D-ribofuranosyl-9H-purine-6(1H)-one

Guanosine is a purine nucleoside composed of a guanine base linked to a ribose sugar via a β-N9-glycosidic bond. It occurs naturally in RNA and is produced industrially through fermentation or chemical synthesis, typically offered at ≥98% purity for pharmaceutical and biotech applications.

As a key intermediate in nucleotide metabolism, guanosine serves as a precursor to guanylic acid (GMP) and its derivatives, which are widely used as flavor enhancers and pharmaceutical actives. Its role in cellular signaling and energy transfer makes it a valuable building block for antiviral, anticancer, and cardiovascular research, as well as a standard in analytical laboratories.
