Chemical Structure
Description
As a certified reference material (CRM), 2,2'-Diiodo-6,6'-dimethylbiphenyl 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.
2,2'-Diiodo-6,6'-dimethylbiphenyl (CAS 134453-96-6) is a high-purity analytical reference standard with the molecular formula C14H12I2 and a molecular weight of 434.05 g/mol.
2,2'-Diiodo-6,6'-dimethylbiphenyl (C14H12I2) contains iodine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
