Chemical Structure
Description
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.
5-Chloro-1-fluoro-2-iodo-3-methoxybenzene (CAS 2383720-94-1), molecular formula C7H5ClFIO and molecular weight 286.47 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C7H5ClFIO, 5-Chloro-1-fluoro-2-iodo-3-methoxybenzene contains a hydroxyl group, an ether linkage, fluorine/chlorine/iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 286.47 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.
