(1E,4E)-1,5-Di(2-thienyl)-1,4-pentadien-3-one (CAS 155669-26-4), molecular formula C13H10OS2 and molecular weight 246.35 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (1E,4E)-1,5-Di(2-thienyl)-1,4-pentadien-3-one (C13H10OS2) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
