Chemical Structure
Description
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 supplies 2-[(E)-2-(2,4-Dichlorophenyl)ethenyl]-1H-imidazole (CAS 213179-56-7), a certified reference material (molecular formula C11H8Cl2N2, MW 239.10 g/mol) for analytical method development and quality control.
2-[(E)-2-(2,4-Dichlorophenyl)ethenyl]-1H-imidazole (C11H8Cl2N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 2-[(E)-2-(2,4-Dichlorophenyl)ethenyl]-1H-imidazole 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.
