About Domperidone Impurity 37
Domperidone Impurity 37 is a specified impurity of Domperidone. 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 C14H19ClN4O3 and a molecular weight of 326.78, with the two-dimensional structure shown above. Because it shares the Domperidone scaffold, it is typically used to track process-related and degradation impurities of Domperidone during method development, forced degradation and stability studies.
Computed from the structure, the compound has a monoisotopic mass of 326.1146 Da, a calculated LogP of 3.03, a topological polar surface area of 88.23 Ų. It presents 1 hydrogen-bond donor and 5 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 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.
