About N2-Nitroso Rolapitant
N2-Nitroso Rolapitant 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 C22H17N7O and a molecular weight of 395.42, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 395.1495 Da, a calculated LogP of 5.07, a topological polar surface area of 118.06 Ų. It presents 1 hydrogen-bond donor and 7 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.
