Chemical Structure
Description
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.
1,2,3-Trifluoro-4,5,6-triiodobenzene (CAS 703404-71-1), molecular formula C6F3I3 and molecular weight 509.77 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6F3I3, 1,2,3-Trifluoro-4,5,6-triiodobenzene contains fluorine/iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 509.77 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).
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.
