About L(-)-Epinephrine
L(-)-Epinephrine is supplied as an analytical reference standard. It is registered under CAS number 51-43-4.
The compound is characterised by its molecular formula C9H13NO3 and a molecular weight of 183.20, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 183.0895 Da, a calculated LogP of 0.35, a topological polar surface area of 72.72 Ų. It presents 4 hydrogen-bond donors and 4 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.
