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 1-(4-Chlorophenyl)-4-hydroxy-6-oxo-1,6-dihydropyridazine-3-carboxamide.
CATO supplies 1-(4-Chlorophenyl)-4-hydroxy-6-oxo-1,6-dihydropyridazine-3-carboxamide (CAS 338405-04-2), a certified reference material (molecular formula C11H8ClN3O3, MW 265.65 g/mol) for analytical method development and quality control.
The molecular framework of 1-(4-Chlorophenyl)-4-hydroxy-6-oxo-1,6-dihydropyridazine-3-carboxamide (C11H8ClN3O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
