1,5-Bis-(4-methoxyphenyl)-3-pentadienone CAS 2051-07-2

Description

The occurrence of 1,5-Bis-(4-methoxyphenyl)-3-pentadienone is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,5-Bis-(4-methoxyphenyl)-3-pentadienone (CAS 2051-07-2), molecular formula C19H18O3 and molecular weight 294.34 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,5-Bis-(4-methoxyphenyl)-3-pentadienone (C19H18O3) is characterized by a steroid core, a hydroxyl group, an ether linkage. 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).

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.
