1-Cyclopropyl-N-ethyl-4-oxo-1,4-dihydroquinoline-3-carboxamide CAS 389118-79-0

Description

1-Cyclopropyl-N-ethyl-4-oxo-1,4-dihydroquinoline-3-carboxamide (CAS 389118-79-0), molecular formula C15H16N2O2 and molecular weight 256.30 g/mol, is a CATO reference standard with documented purity and traceability.

1-Cyclopropyl-N-ethyl-4-oxo-1,4-dihydroquinoline-3-carboxamide (C15H16N2O2) contains a nitrogen-containing heterocyclic scaffold, 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.

As a certified reference material (CRM), 1-Cyclopropyl-N-ethyl-4-oxo-1,4-dihydroquinoline-3-carboxamide 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.
