Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4-(2-Methyl-1H-indol-3-yl)-6-phenyl-4,5-dihydropyridazin-3(2H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 303.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
4-(2-Methyl-1H-indol-3-yl)-6-phenyl-4,5-dihydropyridazin-3(2H)-one (CAS 54104-29-9) is a high-purity analytical reference standard with the molecular formula C19H17N3O and a molecular weight of 303.36 g/mol.
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.
