About Epinephrine /Adrenaline Impurity 118
Epinephrine /Adrenaline Impurity 118 is a specified impurity of Epinephrine /Adrenaline. It has no single publicly registered CAS number, so it is defined by the structure and molecular formula below.
The compound is characterised by its molecular formula C10H14N2O4 and a molecular weight of 226.23, with the two-dimensional structure shown above. Because it shares the Epinephrine /Adrenaline scaffold, it is typically used to track process-related and degradation impurities of Epinephrine /Adrenaline during method development, forced degradation and stability studies.
Computed from the structure, the compound has a monoisotopic mass of 226.0954 Da, a calculated LogP of 1.40, a topological polar surface area of 82.36 Ų. It presents 2 hydrogen-bond donors and 5 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 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.
Available from stock in milligram to gram quantities; larger or custom synthesis requirements are quoted on request.
