Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2E)-1,3-Bis(3-Methoxyphenyl)prop-2-en-1-one.
(2E)-1,3-Bis(3-Methoxyphenyl)prop-2-en-1-one (CAS 72129-75-0), molecular formula C17H16O3 and molecular weight 268.31 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2E)-1,3-Bis(3-Methoxyphenyl)prop-2-en-1-one (C17H16O3) 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.
