About N-Nitroso Proline
N-Nitroso Proline is supplied as an analytical reference standard. It is registered under CAS number 2571-28-0.
The compound is characterised by its molecular formula C5H8N2O3 and a molecular weight of 144.13, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 144.0535 Da, a calculated LogP of 0.22, a topological polar surface area of 69.97 Ų. It presents 1 hydrogen-bond donor and 3 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.
