Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 350.24 g/mol gives 4-Pentyl-4'-iodobiphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Pentyl-4'-iodobiphenyl (CAS 69971-79-5) is a high-purity analytical reference standard with the molecular formula C17H19I and a molecular weight of 350.24 g/mol.
The molecular framework of 4-Pentyl-4'-iodobiphenyl (C17H19I) is characterized by iodine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
