Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 488.38 g/mol gives Dichlorotetrakis(pyridine)ruthenium distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dichlorotetrakis(pyridine)ruthenium (CAS 16997-43-6), molecular formula C20H20Cl2N4Ru and molecular weight 488.38 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Dichlorotetrakis(pyridine)ruthenium (C20H20Cl2N4Ru) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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).
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 Dichlorotetrakis(pyridine)ruthenium 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.
