Chemical Structure
Description
As a certified reference material (CRM), N-(3,4-Dichlorophenyl)-2-({4-[(E)-[(2-hydroxyphenyl)methylidene]amino]phenyl}sulfanyl)acetamide 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.
N-(3,4-Dichlorophenyl)-2-({4-[(E)-[(2-hydroxyphenyl)methylidene]amino]phenyl}sulfanyl)acetamide (CAS 882080-57-1), molecular formula C21H16Cl2N2O2S and molecular weight 431.33 g/mol, is a CATO reference standard with documented purity and traceability.
N-(3,4-Dichlorophenyl)-2-({4-[(E)-[(2-hydroxyphenyl)methylidene]amino]phenyl}sulfanyl)acetamide (C21H16Cl2N2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
