1,2,3,4-naphthalenetetrone 1,2,3,4-tetrahydro-1,2,3,4-tetraoxonaphthalene 30266-58-1 CHEBI:78854 naphthalene-1,2,3,4-tetrone oksolin oxoline (CAS 30266-58-1) is a high-purity analytical reference standard with the molecular formula C10H4O4 and a molecular weight of 188.14 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 1,2,3,4-naphthalenetetrone 1,2,3,4-tetrahydro-1,2,3,4-tetraoxonaphthalene 30266-58-1 CHEBI:78854 naphthalene-1,2,3,4-tetrone oksolin oxoline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.14 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).
