Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (R)-3-(2,6-diethylphenyl)-1-(2-hydroxy-1-phenylethyl)-4,5-dihydro-1H-imidazol-3-ium.
(R)-3-(2,6-diethylphenyl)-1-(2-hydroxy-1-phenylethyl)-4,5-dihydro-1H-imidazol-3-ium (CAS 1630817-20-7) is a high-purity analytical reference standard with the molecular formula C21H27N2O and a molecular weight of 323.45 g/mol.
(R)-3-(2,6-diethylphenyl)-1-(2-hydroxy-1-phenylethyl)-4,5-dihydro-1H-imidazol-3-ium (C21H27N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), (R)-3-(2,6-diethylphenyl)-1-(2-hydroxy-1-phenylethyl)-4,5-dihydro-1H-imidazol-3-ium 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.
