About N-nitroso-desmethyl-dalbavancin a1
N-nitroso-desmethyl-dalbavancin a1 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 C86H95Cl2N11O29 and a molecular weight of 1817.64, with the two-dimensional structure shown above.
Computed from the structure, the compound has a monoisotopic mass of 1815.5674 Da, a calculated LogP of 3.97, a topological polar surface area of 601.94 Ų. It presents 21 hydrogen-bond donors and 30 acceptors. The structure carries 18 defined stereocentres, 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 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. Recommended storage: 2℃ ~ 8℃.
Available from stock in milligram to gram quantities; larger or custom synthesis requirements are quoted on request.
