As a certified reference material (CRM), 3-(3-(3-Isopropylphenyl)-2-oxoimidazolidin-1-yl)benzoic acid 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.
3-(3-(3-Isopropylphenyl)-2-oxoimidazolidin-1-yl)benzoic acid (CAS 651748-77-5), molecular formula C19H20N2O3 and molecular weight 324.37 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(3-(3-Isopropylphenyl)-2-oxoimidazolidin-1-yl)benzoic acid (C19H20N2O3) 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.
