1-(3-Methyl-5,6-diphenylpyridazin-4-yl)ethanone (CAS 62139-88-2), molecular formula C19H16N2O and molecular weight 288.34 g/mol, is a CATO reference standard with documented purity and traceability.
1-(3-Methyl-5,6-diphenylpyridazin-4-yl)ethanone (C19H16N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
