4-Hydroxy-2-oxo-1-pentyl-N-(p-tolyl)-1,2-dihydroquinoline-3-carboxamide CAS 300716-18-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Hydroxy-2-oxo-1-pentyl-N-(p-tolyl)-1,2-dihydroquinoline-3-carboxamide.

4-Hydroxy-2-oxo-1-pentyl-N-(p-tolyl)-1,2-dihydroquinoline-3-carboxamide (CAS 300716-18-1) is a high-purity analytical reference standard with the molecular formula C22H24N2O3 and a molecular weight of 364.44 g/mol.

The molecular framework of 4-Hydroxy-2-oxo-1-pentyl-N-(p-tolyl)-1,2-dihydroquinoline-3-carboxamide (C22H24N2O3) 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 the protonation state of its nitrogen-containing groups, 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.
