5,7-Dichloropyrido[3,4-d]pyridazin-4(3H)-one CAS 1390656-66-2

Description

The occurrence of 5,7-Dichloropyrido[3,4-d]pyridazin-4(3H)-one is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5,7-Dichloropyrido[3,4-d]pyridazin-4(3H)-one (CAS 1390656-66-2), a certified reference material (molecular formula C7H3Cl2N3O, MW 216.02 g/mol) for analytical method development and quality control.

The molecular framework of 5,7-Dichloropyrido[3,4-d]pyridazin-4(3H)-one (C7H3Cl2N3O) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.

CATO manufactures 5,7-Dichloropyrido[3,4-d]pyridazin-4(3H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
