Chemical Structure

4,5-Diphenyl-1H-pyrazol-3-amine CAS 63633-46-5 chemical structure

Description

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.

4,5-Diphenyl-1H-pyrazol-3-amine (CAS 63633-46-5) is a high-purity analytical reference standard with the molecular formula C15H13N3 and a molecular weight of 235.28 g/mol.

The molecular framework of 4,5-Diphenyl-1H-pyrazol-3-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).

CATO manufactures 4,5-Diphenyl-1H-pyrazol-3-amine 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.
