4-{[(2-chlorophenyl)amino]methylidene}-3-phenyl-4,5-dihydro-1H-pyrazol-5-one CAS 338975-60-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-{[(2-chlorophenyl)amino]methylidene}-3-phenyl-4,5-dihydro-1H-pyrazol-5-one.

CATO supplies 4-{[(2-chlorophenyl)amino]methylidene}-3-phenyl-4,5-dihydro-1H-pyrazol-5-one (CAS 338975-60-3), a certified reference material (molecular formula C16H12ClN3O, MW 297.74 g/mol) for analytical method development and quality control.

4-{[(2-chlorophenyl)amino]methylidene}-3-phenyl-4,5-dihydro-1H-pyrazol-5-one (C16H12ClN3O) 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.

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.
