The occurrence of (2Z)-6-Hydroxy-2-[(2E)-3-phenylprop-2-en-1-ylidene]-1-benzofuran-3(2H)-one 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.
(2Z)-6-Hydroxy-2-[(2E)-3-phenylprop-2-en-1-ylidene]-1-benzofuran-3(2H)-one (CAS 88281-20-3) is a high-purity analytical reference standard with the molecular formula C17H12O3 and a molecular weight of 264.28 g/mol.
The molecular framework of (2Z)-6-Hydroxy-2-[(2E)-3-phenylprop-2-en-1-ylidene]-1-benzofuran-3(2H)-one (C17H12O3) 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 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.
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.
