Chemical Structure

1-(2-(4-Hydroxynaphthalen-1-yl)benzofuran-3-yl)ethanone CAS 61639-35-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 302.32 g/mol gives 1-(2-(4-Hydroxynaphthalen-1-yl)benzofuran-3-yl)ethanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(2-(4-Hydroxynaphthalen-1-yl)benzofuran-3-yl)ethanone (CAS 61639-35-8), molecular formula C20H14O3 and molecular weight 302.32 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-(2-(4-Hydroxynaphthalen-1-yl)benzofuran-3-yl)ethanone (C20H14O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 302.32 g/mol, it falls into the moderately-high-molecular-weight range. 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.
