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.
2-(4-((3-Chlorobenzyl)oxy)benzylidene)malononitrile (CAS 883822-92-2) is a high-purity analytical reference standard with the molecular formula C17H11ClN2O and a molecular weight of 294.74 g/mol.
2-(4-((3-Chlorobenzyl)oxy)benzylidene)malononitrile (C17H11ClN2O) contains a steroid core, an amide group, 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).
As a certified reference material (CRM), 2-(4-((3-Chlorobenzyl)oxy)benzylidene)malononitrile 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.
