Chemical Structure
Description
Perfluoro-tert-butyl iodide (CAS 4459-18-1), molecular formula C4F9I and molecular weight 345.93 g/mol, is a CATO reference standard with documented purity and traceability.
Perfluoro-tert-butyl iodide (C4F9I) contains fluorine/iodine substitution. 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.
As a certified reference material (CRM), Perfluoro-tert-butyl iodide 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.
