3-Phenyl-4-({[3-(trifluoromethyl)phenyl]amino}methylidene)-4,5-dihydro-1H-pyrazol-5-one CAS 338975-63-6 chemical structure

Description

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

3-Phenyl-4-({[3-(trifluoromethyl)phenyl]amino}methylidene)-4,5-dihydro-1H-pyrazol-5-one (CAS 338975-63-6), molecular formula C17H12F3N3O and molecular weight 331.29 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-Phenyl-4-({[3-(trifluoromethyl)phenyl]amino}methylidene)-4,5-dihydro-1H-pyrazol-5-one (C17H12F3N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 331.29 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures 3-Phenyl-4-({[3-(trifluoromethyl)phenyl]amino}methylidene)-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.
