Chemical Structure
Description
The molecular framework of 1-{[1,1'-biphenyl]-2-yl}-3,4,5-trimethyl-1H-pyrazole (C18H18N2) 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).
1-{[1,1'-biphenyl]-2-yl}-3,4,5-trimethyl-1H-pyrazole (CAS 956962-20-2) is a high-purity analytical reference standard with the molecular formula C18H18N2 and a molecular weight of 262.35 g/mol.
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), 1-{[1,1'-biphenyl]-2-yl}-3,4,5-trimethyl-1H-pyrazole 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.
