Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 235.28 g/mol gives 1,4-diphenyl-1H-pyrazol-5-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1,4-diphenyl-1H-pyrazol-5-amine (CAS 108719-40-0), a certified reference material (molecular formula C15H13N3, MW 235.28 g/mol) for analytical method development and quality control.
The molecular framework of 1,4-diphenyl-1H-pyrazol-5-amine (C15H13N3) 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.
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.
