About 25-Hydroxy Doxercalciferol
25-Hydroxy Doxercalciferol is supplied as an analytical reference standard. It is registered under CAS number 60133-18-8.
The compound is characterised by its molecular formula C28H44O3 and a molecular weight of 428.65, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 428.3290 Da, a calculated LogP of 5.73, a topological polar surface area of 60.69 Ų. It presents 3 hydrogen-bond donors and 3 acceptors. The structure carries 7 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. Recommended storage: 2℃ ~ 8℃.
Available from stock in milligram to gram quantities; larger or custom synthesis requirements are quoted on request.
