Chemical Structure

(E)-4-methoxy-(2,2'-bipyridine)-6-carbaldehyde oxime (E)-4-methoxy-2,2'-bipyridyl-6-aldoxime (E)-N-hydroxy-1-(4-methoxy-2,2'-bipyridin-6-yl)methanimine 21802-37-9 CHEBI:69231 caerulomycin A cerulomycin CAS 21802-37-9 chemical structure

Description

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (E)-4-methoxy-(2,2'-bipyridine)-6-carbaldehyde oxime (E)-4-methoxy-2,2'-bipyridyl-6-aldoxime (E)-N-hydroxy-1-(4-methoxy-2,2'-bipyridin-6-yl)methanimine 21802-37-9 CHEBI:69231 caerulomycin A cerulomycin is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 241.33 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).
