Chemical Structure
Description
CATO supplies 4-(4-Fluorophenyl)-3,6-diphenylpyridazine (CAS 838814-77-0), a certified reference material (molecular formula C22H15FN2, MW 326.37 g/mol) for analytical method development and quality control.
The molecular framework of 4-(4-Fluorophenyl)-3,6-diphenylpyridazine (C22H15FN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
