N-(6,8-Dichloro-4-hydroxy-2-oxo-1,2-dihydroquinolin-3-yl)acetamide CAS 64002-02-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(6,8-Dichloro-4-hydroxy-2-oxo-1,2-dihydroquinolin-3-yl)acetamide.

CATO supplies N-(6,8-Dichloro-4-hydroxy-2-oxo-1,2-dihydroquinolin-3-yl)acetamide (CAS 64002-02-4), a certified reference material (molecular formula C11H8Cl2N2O3, MW 287.10 g/mol) for analytical method development and quality control.

N-(6,8-Dichloro-4-hydroxy-2-oxo-1,2-dihydroquinolin-3-yl)acetamide (C11H8Cl2N2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), N-(6,8-Dichloro-4-hydroxy-2-oxo-1,2-dihydroquinolin-3-yl)acetamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
