3-Butyl-1-(4-chlorophenyl)-4,5-dihydro-1H-pyrazol-5-one (CAS 118048-90-1) is a high-purity analytical reference standard with the molecular formula C13H15ClN2O and a molecular weight of 250.72 g/mol.
3-Butyl-1-(4-chlorophenyl)-4,5-dihydro-1H-pyrazol-5-one (C13H15ClN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
