(5S)-(-)-2,2,3-Trimethyl-5-benzyl-4-imidazolidinone dichloroacetic acid (5S)-2,2,3-Trimethyl-5-phenylmethyl-4-imidazolidinone dichloroacetic acid 345358-20-5 (CAS 345358-20-5) is a high-purity analytical reference standard with the molecular formula C13H24N2OC2H2Cl2O2 and a molecular weight of 353.28 g/mol.
The molecular framework of (5S)-(-)-2,2,3-Trimethyl-5-benzyl-4-imidazolidinone dichloroacetic acid (5S)-2,2,3-Trimethyl-5-phenylmethyl-4-imidazolidinone dichloroacetic acid 345358-20-5 (C13H24N2OC2H2Cl2O2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
As a certified reference material (CRM), (5S)-(-)-2,2,3-Trimethyl-5-benzyl-4-imidazolidinone dichloroacetic acid (5S)-2,2,3-Trimethyl-5-phenylmethyl-4-imidazolidinone dichloroacetic acid 345358-20-5 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.
