Chemical Structure

Rubidium-<SUP>85</SUP>Rb chloride CAS 34007-79-9 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.

Rubidium-<SUP>85</SUP>Rb chloride (CAS 34007-79-9) is a high-purity analytical reference standard with the molecular formula Cl[85Rb] and a molecular weight of 120.36 g/mol.

Rubidium-<SUP>85</SUP>Rb chloride (Cl[85Rb]) contains chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO manufactures Rubidium-<SUP>85</SUP>Rb 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.
