Chemical Structure
Description
CATO supplies 6-(4-Ethylphenyl)-3-(ethylthio)-[1,2,4]triazolo[4,3-b]pyridazine (CAS 894047-92-8), a certified reference material (molecular formula C15H16N4S, MW 284.38 g/mol) for analytical method development and quality control.
The molecular framework of 6-(4-Ethylphenyl)-3-(ethylthio)-[1,2,4]triazolo[4,3-b]pyridazine (C15H16N4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
