About 1,2-Dihydrodesonide
1,2-Dihydrodesonide is supplied as an analytical reference standard. It is registered under CAS number 638-93-7.
The compound is characterised by its molecular formula C24H34O6 and a molecular weight of 418.52, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 418.2355 Da, a calculated LogP of 2.55, a topological polar surface area of 93.06 Ų. It presents 2 hydrogen-bond donors and 6 acceptors. The structure carries 8 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: -20℃±5℃.
Available from stock in milligram to gram quantities; larger or custom synthesis requirements are quoted on request.
