About Olopatadine Impurity 58
Olopatadine Impurity 58 is supplied as an analytical reference standard. 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 C19H16O3 and a molecular weight of 292.33, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 292.1099 Da, a calculated LogP of 3.82, a topological polar surface area of 46.53 Ų. It presents 1 hydrogen-bond donor and 2 acceptors. 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.
Available from stock in milligram to gram quantities; larger or custom synthesis requirements are quoted on request.
