5,6-Dimethyl-10-phenyl-2,9-diazatricyclo[9.4.0.0^{3,8}]pentadeca-1(11),3,5,7-tetraen-12-one; ethanol (CAS 1823183-78-3) is a high-purity analytical reference standard with the molecular formula C21H22N2OC2H6O and a molecular weight of 364.49 g/mol.
The molecular framework of 5,6-Dimethyl-10-phenyl-2,9-diazatricyclo[9.4.0.0^{3,8}]pentadeca-1(11),3,5,7-tetraen-12-one; ethanol (C21H22N2OC2H6O) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 5,6-Dimethyl-10-phenyl-2,9-diazatricyclo[9.4.0.0^{3,8}]pentadeca-1(11),3,5,7-tetraen-12-one; ethanol 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.
