Chemical Structure
Description
The occurrence of 2-[(E)-2-(2-chlorophenyl)ethenyl]-1-[(2,4-dichlorophenyl)methyl]-1H-1,3-benzodiazole 2J-561S 338772-21-7 is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-[(E)-2-(2-chlorophenyl)ethenyl]-1-[(2,4-dichlorophenyl)methyl]-1H-1,3-benzodiazole 2J-561S 338772-21-7 (CAS 338772-21-7), molecular formula C22H15Cl3N2 and molecular weight 413.73 g/mol, is a CATO reference standard with documented purity and traceability.
2-[(E)-2-(2-chlorophenyl)ethenyl]-1-[(2,4-dichlorophenyl)methyl]-1H-1,3-benzodiazole 2J-561S 338772-21-7 (C22H15Cl3N2) 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. 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.
