Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

4-{[(4-chlorophenyl)amino]methylidene}-3-phenyl-4,5-dihydro-1H-pyrazol-5-one (CAS 338975-62-5), molecular formula C16H12ClN3O and molecular weight 297.74 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-{[(4-chlorophenyl)amino]methylidene}-3-phenyl-4,5-dihydro-1H-pyrazol-5-one (C16H12ClN3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
