1-(4-Chlorophenyl)-2-(4-(4-chlorophenyl)-2-((3,4-dichlorobenzyl)thio)-1H-imidazol-1-yl)ethan-1-one CAS 477846-78-9

Description

As a certified reference material (CRM), 1-(4-Chlorophenyl)-2-(4-(4-chlorophenyl)-2-((3,4-dichlorobenzyl)thio)-1H-imidazol-1-yl)ethan-1-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

1-(4-Chlorophenyl)-2-(4-(4-chlorophenyl)-2-((3,4-dichlorobenzyl)thio)-1H-imidazol-1-yl)ethan-1-one (CAS 477846-78-9), molecular formula C24H16Cl4N2OS and molecular weight 522.27 g/mol, is a CATO reference standard with documented purity and traceability.

1-(4-Chlorophenyl)-2-(4-(4-chlorophenyl)-2-((3,4-dichlorobenzyl)thio)-1H-imidazol-1-yl)ethan-1-one (C24H16Cl4N2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 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. 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.
