Chemical Structure

Diethyl 5,6-diphenylpyridazine-3,4-dicarboxylate CAS 253144-68-2 chemical structure

Description

CATO manufactures Diethyl 5,6-diphenylpyridazine-3,4-dicarboxylate 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.

Diethyl 5,6-diphenylpyridazine-3,4-dicarboxylate (CAS 253144-68-2) is a high-purity analytical reference standard with the molecular formula C22H20N2O4 and a molecular weight of 376.41 g/mol.

The molecular framework of Diethyl 5,6-diphenylpyridazine-3,4-dicarboxylate (C22H20N2O4) is characterized by a flavonoid 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
