Chemical Structure

1-(2-Ethyl-9H-fluoren-9-yl)ethanone CAS 62731-46-8 chemical structure

Description

The occurrence of 1-(2-Ethyl-9H-fluoren-9-yl)ethanone 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-(2-Ethyl-9H-fluoren-9-yl)ethanone (CAS 62731-46-8) is a high-purity analytical reference standard with the molecular formula C17H16O and a molecular weight of 236.31 g/mol.

Structurally, 1-(2-Ethyl-9H-fluoren-9-yl)ethanone (C17H16O) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 236.31 g/mol, it falls into the medium-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.
