Description
CATO supplies 5-methyl-1-(3-nitrophenyl)-2,3-dihydro-1H-imidazol-2-one (CAS 13870-56-9), a certified reference material (molecular formula C10H9N3O3, MW 219.20 g/mol) for analytical method development and quality control.
The molecular framework of 5-methyl-1-(3-nitrophenyl)-2,3-dihydro-1H-imidazol-2-one (C10H9N3O3) is characterized by an amino-acid-derived structure, 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 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.
As a certified reference material (CRM), 5-methyl-1-(3-nitrophenyl)-2,3-dihydro-1H-imidazol-2-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.
