Chemical Structure
Description
The occurrence of Chloropentaammineruthenium(II) chloride is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Chloropentaammineruthenium(II) chloride (CAS 137729-23-8) is a high-purity analytical reference standard with the molecular formula H15ClN5RuCl and a molecular weight of 257.12 g/mol.
Owing to chlorine substitution, Chloropentaammineruthenium(II) chloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 Chloropentaammineruthenium(II) chloride 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.
