Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-(4-Ethoxyphenyl)-6-((2-methylbenzyl)thio)pyridazine (CAS 896054-47-0), molecular formula C20H20N2OS and molecular weight 336.45 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(4-Ethoxyphenyl)-6-((2-methylbenzyl)thio)pyridazine (C20H20N2OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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.
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.
