Compared with other compounds in its class, the molecular weight of 306.10 g/mol gives 4-Iodo-9H-fluoren-9-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Iodo-9H-fluoren-9-one (CAS 883-33-0) is a high-purity analytical reference standard with the molecular formula C13H7IO and a molecular weight of 306.10 g/mol.
The molecular framework of 4-Iodo-9H-fluoren-9-one (C13H7IO) is characterized by a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures 4-Iodo-9H-fluoren-9-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
