4,4'-Diiodo-2,2'-dimethyl-1,1'-biphenyl CAS 69571-02-4

Description

The occurrence of 4,4'-Diiodo-2,2'-dimethyl-1,1'-biphenyl is closely related to iodine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4,4'-Diiodo-2,2'-dimethyl-1,1'-biphenyl (CAS 69571-02-4), a certified reference material (molecular formula C14H12I2, MW 434.05 g/mol) for analytical method development and quality control.

4,4'-Diiodo-2,2'-dimethyl-1,1'-biphenyl (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 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
