2-(4-Aminophenyl)-4-chloro-5-fluoropyridazin-3(2H)-one CAS 89593-79-3

Description

Compared with other compounds in its class, the molecular weight of 239.63 g/mol gives 2-(4-Aminophenyl)-4-chloro-5-fluoropyridazin-3(2H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(4-Aminophenyl)-4-chloro-5-fluoropyridazin-3(2H)-one (CAS 89593-79-3), molecular formula C10H7ClFN3O and molecular weight 239.63 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(4-Aminophenyl)-4-chloro-5-fluoropyridazin-3(2H)-one (C10H7ClFN3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 2-(4-Aminophenyl)-4-chloro-5-fluoropyridazin-3(2H)-one 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.
