Chemical Structure
Description
The occurrence of 1,4-Diphenyl-2,3-butanedione is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,4-Diphenyl-2,3-butanedione (CAS 13832-10-5), molecular formula C16H14O2 and molecular weight 238.28 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 1,4-Diphenyl-2,3-butanedione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 238.28 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
