Chemical Structure
Description
Structurally, 1-(9-Chloro-9H-fluoren-9-yl)ethanone (C15H11ClO) contains a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. 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 242.70 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.
CATO supplies 1-(9-Chloro-9H-fluoren-9-yl)ethanone (CAS 62731-58-2), a certified reference material (molecular formula C15H11ClO, MW 242.70 g/mol) for analytical method development and quality control.
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.
