Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, N-nitroso-desmethyl-dalbavancin b2 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1845.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO supplies N-nitroso-desmethyl-dalbavancin b2 (CAS CATO-C4X-160242), a certified reference material (molecular formula C88H99Cl2N11O29, MW 1845.69 g/mol) for analytical method development and quality control.
