Description
CATO manufactures 2-Chloro-1-fluoro-4-iodo-3-methylbenzene 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.
2-Chloro-1-fluoro-4-iodo-3-methylbenzene (CAS 1807166-56-8), molecular formula C7H5ClFI and molecular weight 270.47 g/mol, is a CATO reference standard with documented purity and traceability.
2-Chloro-1-fluoro-4-iodo-3-methylbenzene (C7H5ClFI) 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.
