Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 406.00 g/mol gives 2,2'-Diiodobiphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,2'-Diiodobiphenyl (CAS 2236-52-4), a certified reference material (molecular formula C12H8I2, MW 406.00 g/mol) for analytical method development and quality control.
Based on its molecular formula C12H8I2, 2,2'-Diiodobiphenyl contains iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 406.00 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
CATO manufactures 2,2'-Diiodobiphenyl 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.
