Chemical Structure
Description
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.
CATO supplies 5-(6-Methyl-2-phenylquinolin-4-yl)-1,3,4-oxadiazole-2(3H)-thione (CAS 90074-17-2), a certified reference material (molecular formula C18H13N3OS, MW 319.38 g/mol) for analytical method development and quality control.
The molecular framework of 5-(6-Methyl-2-phenylquinolin-4-yl)-1,3,4-oxadiazole-2(3H)-thione (C18H13N3OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
