Guanine hydrochloride is one of the basic components of nucleic acids (DNA and RNA). Guanine hydrochloride is a purine derivative consisting of a fused pyrimidine-imidazole ring system with conjugated double bonds. Guanine hydrochloride has the potential to serve as a large nitrogen reservoir.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
