Description
CATO manufactures 1,4-Diiodo-2,5-bis(octyloxy)benzene 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.
CATO supplies 1,4-Diiodo-2,5-bis(octyloxy)benzene (CAS 145483-68-7), a certified reference material (molecular formula C22H36I2O2, MW 586.33 g/mol) for analytical method development and quality control.
The molecular framework of 1,4-Diiodo-2,5-bis(octyloxy)benzene (C22H36I2O2) is characterized by a steroid core, a hydroxyl group, an ether linkage, iodine substitution. 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.
