Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5,5-Dimethyl-2-(naphthalen-2-yloxy)oxazol-4(5H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 255.27 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).
5,5-Dimethyl-2-(naphthalen-2-yloxy)oxazol-4(5H)-one (CAS 73372-82-4) is a high-purity analytical reference standard with the molecular formula C15H13NO3 and a molecular weight of 255.27 g/mol.
