About Guanosine 5'-Diphosphate
Guanosine 5'-Diphosphate is supplied as an analytical reference standard. It is registered under CAS number 146-91-8.
The compound is characterised by its molecular formula C10H15N5O11P2 and a molecular weight of 443.20, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 443.0243 Da, a calculated LogP of -2.45, a topological polar surface area of 252.57 Ų. It presents 7 hydrogen-bond donors and 11 acceptors. The structure carries 5 defined stereocentres, which is relevant wherever a stereochemically defined standard is required. These values are commonly used to anticipate chromatographic retention and to plan ionisation conditions during method development.
Each pack ships with a certificate of analysis reporting purity of 95%+ together with the supporting analytical data — HNMR, MS and HPLC or GC traces — so the material can be released straight into your own QC workflow.
Available from stock in milligram to gram quantities; larger or custom synthesis requirements are quoted on request.
