Chemical Structure
Description
1-(3-Methyl-3,4-dihydroquinolin-1(2H)-yl)ethanone (CAS 950589-56-7) is a high-purity analytical reference standard with the molecular formula C12H15NO and a molecular weight of 189.25 g/mol.
1-(3-Methyl-3,4-dihydroquinolin-1(2H)-yl)ethanone (C12H15NO) contains a nitrogen-containing heterocyclic scaffold, 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 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.
As a certified reference material (CRM), 1-(3-Methyl-3,4-dihydroquinolin-1(2H)-yl)ethanone 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.
