Chemical Structure
Description
The occurrence of 4-(1,3-Diphenyl-4,5-dihydro-1H-pyrazol-5-yl)aniline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-(1,3-Diphenyl-4,5-dihydro-1H-pyrazol-5-yl)aniline (CAS 10179-54-1), a certified reference material (molecular formula C21H19N3, MW 313.40 g/mol) for analytical method development and quality control.
The molecular framework of 4-(1,3-Diphenyl-4,5-dihydro-1H-pyrazol-5-yl)aniline (C21H19N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-(1,3-Diphenyl-4,5-dihydro-1H-pyrazol-5-yl)aniline meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
