Description
As a certified reference material (CRM), 4-Chloro-2-fluoroiodobenzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
4-Chloro-2-fluoroiodobenzene (CAS 6797-79-1), molecular formula C6H3ClFI and molecular weight 256.44 g/mol, is a CATO reference standard with documented purity and traceability.
4-Chloro-2-fluoroiodobenzene (C6H3ClFI) contains fluorine/chlorine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
