Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
4-(6-Ethoxy-2-methyl-4-thioxo-1,4-dihydroquinolin-3-yl)butan-2-one (CAS 57292-30-5) is a high-purity analytical reference standard with the molecular formula C18H19ClN2O2S and a molecular weight of 362.87 g/mol.
The molecular framework of 4-(6-Ethoxy-2-methyl-4-thioxo-1,4-dihydroquinolin-3-yl)butan-2-one (C18H19ClN2O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
