Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(4Z)-4-{[(4-chlorophenyl)amino]methylidene}-1-phenyl-3-(trifluoromethyl)-4,5-dihydro-1H-pyrazol-5-one (CAS 314747-18-7) is a high-purity analytical reference standard with the molecular formula C17H11ClF3N3O and a molecular weight of 365.74 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, (4Z)-4-{[(4-chlorophenyl)amino]methylidene}-1-phenyl-3-(trifluoromethyl)-4,5-dihydro-1H-pyrazol-5-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 365.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures (4Z)-4-{[(4-chlorophenyl)amino]methylidene}-1-phenyl-3-(trifluoromethyl)-4,5-dihydro-1H-pyrazol-5-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
