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-(4,5-Dichloro-1H-imidazol-1-yl)phenyl)imino)methyl)-3-hydroxy-1H-inden-1-one (CAS 1024316-38-8), molecular formula C19H11Cl2N3O2 and molecular weight 384.22 g/mol, is a CATO reference standard with documented purity and traceability.
2-(((4-(4,5-Dichloro-1H-imidazol-1-yl)phenyl)imino)methyl)-3-hydroxy-1H-inden-1-one (C19H11Cl2N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 2-(((4-(4,5-Dichloro-1H-imidazol-1-yl)phenyl)imino)methyl)-3-hydroxy-1H-inden-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.
