About Sunitinib
Sunitinib is supplied as an analytical reference standard. It is registered under CAS number 557795-19-4.
The compound is characterised by its molecular formula C22H27FN4O2 and a molecular weight of 398.47, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 398.2118 Da, a calculated LogP of 3.33, a topological polar surface area of 77.23 Ų. It presents 3 hydrogen-bond donors and 3 acceptors. 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. Recommended storage: 2℃ ~ 8℃.
Available from stock in milligram to gram quantities; larger or custom synthesis requirements are quoted on request.
