About (1R)-(-)-Nopol
(1R)-(-)-Nopol is supplied as an analytical reference standard. It is registered under CAS number 35836-73-8.
The compound is characterised by its molecular formula C11H18O and a molecular weight of 166.26, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 166.1358 Da, a calculated LogP of 2.36, a topological polar surface area of 20.23 Ų. It presents 1 hydrogen-bond donor and 1 acceptor. The structure carries 2 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.
