Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 306.14 g/mol gives 9-(Iodomethyl)-9H-fluorene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
9-(Iodomethyl)-9H-fluorene (CAS 73283-56-4), molecular formula C14H11I and molecular weight 306.14 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H11I, 9-(Iodomethyl)-9H-fluorene contains iodine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 306.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
