Chemical Structure

1,4-Diphenylbut-2-ene-1,4-dione CAS 4070-75-1 chemical structure

Description

The molecular framework of 1,4-Diphenylbut-2-ene-1,4-dione (C16H12O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

1,4-Diphenylbut-2-ene-1,4-dione (CAS 4070-75-1), molecular formula C16H12O2 and molecular weight 236.27 g/mol, is a CATO reference standard with documented purity and traceability.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
