Chemical Structure
Description
4-Isopropyl-4-methyldiphenyliodonium Tetrakis(pentafluorophenyl)borate (CAS 1878128-77-8) is a high-purity analytical reference standard with the molecular formula C24BF20C16H18I and a molecular weight of 1016.25 g/mol.
Structurally, 4-Isopropyl-4-methyldiphenyliodonium Tetrakis(pentafluorophenyl)borate (C24BF20C16H18I) contains fluorine/iodine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 21.5, corresponding to approximately 21 ring(s) or double-bond equivalent(s). With a molecular weight of 1016.25 g/mol, it falls into the high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 4-Isopropyl-4-methyldiphenyliodonium Tetrakis(pentafluorophenyl)borate 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.
