Chemical Structure
Description
As a certified reference material (CRM), N1-[(1E)-(2-Methoxyphenyl)methylene]-4-phenyl-1H-imidazole-1,2-diamine 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.
N1-[(1E)-(2-Methoxyphenyl)methylene]-4-phenyl-1H-imidazole-1,2-diamine (CAS 1993501-23-7), molecular formula C17H16N4O and molecular weight 292.34 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N1-[(1E)-(2-Methoxyphenyl)methylene]-4-phenyl-1H-imidazole-1,2-diamine (C17H16N4O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
