About alpha-Tocopherol spiro-dimer
alpha-Tocopherol spiro-dimer is supplied as an analytical reference standard. It is registered under CAS number 1604-73-5.
The compound is characterised by its molecular formula C58H96O4 and a molecular weight of 857.38, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 856.7309 Da, a calculated LogP of 17.07, a topological polar surface area of 44.76 Ų. It presents 0 hydrogen-bond donors and 4 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.
