Chemical Structure
Description
As a certified reference material (CRM), 4,5-dimethyl-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.
4,5-dimethyl-2,3-dihydro-1H-imidazol-2-one (CAS 1072-89-5), molecular formula C5H8N2O and molecular weight 112.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4,5-dimethyl-2,3-dihydro-1H-imidazol-2-one (C5H8N2O) is characterized by 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.
