Chemical Structure

trans,trans-1,5-Diphenyl-1,4-pentadien-3-one CAS 35225-79-7 chemical structure

Description

trans,trans-1,5-Diphenyl-1,4-pentadien-3-one (CAS 35225-79-7), molecular formula C17H14O and molecular weight 234.29 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C17H14O, trans,trans-1,5-Diphenyl-1,4-pentadien-3-one contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 234.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
