Chemical Structure
Description
As a certified reference material (CRM), (3Z)-3-{[(2-methylphenyl)methoxy]imino}-1-phenyl-2,3-dihydro-1H-indol-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.
(3Z)-3-{[(2-methylphenyl)methoxy]imino}-1-phenyl-2,3-dihydro-1H-indol-2-one (CAS 478261-39-1) is a high-purity analytical reference standard with the molecular formula C22H18N2O2 and a molecular weight of 342.39 g/mol.
(3Z)-3-{[(2-methylphenyl)methoxy]imino}-1-phenyl-2,3-dihydro-1H-indol-2-one (C22H18N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
