Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 309.38 g/mol gives Ethyl 4-(phenylthio)quinoline-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl 4-(phenylthio)quinoline-3-carboxylate (CAS 88350-87-2), a certified reference material (molecular formula C18H15NO2S, MW 309.38 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 4-(phenylthio)quinoline-3-carboxylate (C18H15NO2S) is characterized by a steroid core, an amide group, a sulfone 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
