Chemical Structure
Description
1,1,2,2-Tetra(1H-pyrazol-1-yl)ethane (CAS 1073267-95-4) is a high-purity analytical reference standard with the molecular formula C14H14N8 and a molecular weight of 294.31 g/mol.
The molecular framework of 1,1,2,2-Tetra(1H-pyrazol-1-yl)ethane (C14H14N8) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).
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 1,1,2,2-Tetra(1H-pyrazol-1-yl)ethane 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.
