Ethyl 2-{[4'-(2-ethoxy-2-oxo-1-phenylethoxy)-[1,1'-biphenyl]-4-yl]oxy}-2-phenylacetate CAS 320423-70-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 510.58 g/mol gives Ethyl 2-{[4'-(2-ethoxy-2-oxo-1-phenylethoxy)-[1,1'-biphenyl]-4-yl]oxy}-2-phenylacetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 2-{[4'-(2-ethoxy-2-oxo-1-phenylethoxy)-[1,1'-biphenyl]-4-yl]oxy}-2-phenylacetate (CAS 320423-70-9), molecular formula C32H30O6 and molecular weight 510.58 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Ethyl 2-{[4'-(2-ethoxy-2-oxo-1-phenylethoxy)-[1,1'-biphenyl]-4-yl]oxy}-2-phenylacetate (C32H30O6) 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 the polarity and ionization state of its functional groups, 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.
