Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 336.21 g/mol gives 4-Butyl-4'-iodobiphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Butyl-4'-iodobiphenyl (CAS 199982-02-0), a certified reference material (molecular formula C16H17I, MW 336.21 g/mol) for analytical method development and quality control.
The molecular framework of 4-Butyl-4'-iodobiphenyl (C16H17I) 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 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.
CATO manufactures 4-Butyl-4'-iodobiphenyl 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.
