3-Chloro-2-(3,4-dichlorophenyl)-9H-fluoren-9-one CAS 7145-64-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Chloro-2-(3,4-dichlorophenyl)-9H-fluoren-9-one.

3-Chloro-2-(3,4-dichlorophenyl)-9H-fluoren-9-one (CAS 7145-64-4) is a high-purity analytical reference standard with the molecular formula C19H9Cl3O and a molecular weight of 359.63 g/mol.

Based on its molecular formula C19H9Cl3O, 3-Chloro-2-(3,4-dichlorophenyl)-9H-fluoren-9-one contains a steroid core, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 359.63 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.
