Chemical Structure
Description
CATO supplies 2-((8-Hydroxyquinolin-5-yl)imino)-1-(p-tolyl)ethanone (CAS 26942-57-4), a certified reference material (molecular formula C18H14N2O2, MW 290.32 g/mol) for analytical method development and quality control.
The molecular framework of 2-((8-Hydroxyquinolin-5-yl)imino)-1-(p-tolyl)ethanone (C18H14N2O2) is characterized by a steroid core, an amide 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
