Chemical Structure

N-(9H-Fluoren-2-yl)benzamide CAS 3671-78-1 chemical structure

Description

N-(9H-Fluoren-2-yl)benzamide (CAS 3671-78-1) is a high-purity analytical reference standard with the molecular formula C20H15NO and a molecular weight of 285.34 g/mol.

Structurally, N-(9H-Fluoren-2-yl)benzamide (C20H15NO) contains a steroid core, an amide group, 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 285.34 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.
