About D-Nebivolol (SR,RR)
D-Nebivolol (SR,RR) is supplied as an analytical reference standard. It is registered under CAS number 118457-15-1.
The compound is characterised by its molecular formula C22H25F2NO4 and a molecular weight of 405.44, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 405.1752 Da, a calculated LogP of 2.36, a topological polar surface area of 70.95 Ų. It presents 3 hydrogen-bond donors and 5 acceptors. The structure carries 4 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.
