Chemical Structure
Description
Structurally, 6-Benzoyl-2-(4-chlorophenyl)-5-(trifluoromethyl)-2,3-dihydropyridazin-3-one (C18H10ClF3N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 378.73 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
6-Benzoyl-2-(4-chlorophenyl)-5-(trifluoromethyl)-2,3-dihydropyridazin-3-one (CAS 478032-30-3), molecular formula C18H10ClF3N2O2 and molecular weight 378.73 g/mol, is a CATO reference standard with documented purity and traceability.
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.
