4-((5-Chloro-6-oxo-1-phenyl-1,6-dihydropyridazin-4-yl)oxy)-3-methoxybenzoic acid CAS 881463-44-1

Description

As a certified reference material (CRM), 4-((5-Chloro-6-oxo-1-phenyl-1,6-dihydropyridazin-4-yl)oxy)-3-methoxybenzoic acid 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.

4-((5-Chloro-6-oxo-1-phenyl-1,6-dihydropyridazin-4-yl)oxy)-3-methoxybenzoic acid (CAS 881463-44-1) is a high-purity analytical reference standard with the molecular formula C18H13ClN2O5 and a molecular weight of 372.76 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 4-((5-Chloro-6-oxo-1-phenyl-1,6-dihydropyridazin-4-yl)oxy)-3-methoxybenzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 372.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
