About (R)-Ketorolac
(R)-Ketorolac is supplied as an analytical reference standard. It is registered under CAS number 66635-93-6.
The compound is characterised by its molecular formula C15H13NO3 and a molecular weight of 255.27, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 255.0895 Da, a calculated LogP of 2.29, a topological polar surface area of 59.30 Ų. It presents 1 hydrogen-bond donor and 2 acceptors. The structure carries 1 defined stereocentre, 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.
