Chemical Structure
Description
2-(9H-Fluoren-9-yl)malononitrile (CAS 6235-14-9) is a high-purity analytical reference standard with the molecular formula C10H6Cl6O and a molecular weight of 354.87 g/mol.
Based on its molecular formula C10H6Cl6O, 2-(9H-Fluoren-9-yl)malononitrile contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 354.87 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
