Description
CATO manufactures rubidium fluoride 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.
rubidium fluoride (CAS 13446-74-7) is a high-purity analytical reference standard with the molecular formula RbF and a molecular weight of 104.47 g/mol.
Owing to fluorine substitution, rubidium fluoride is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 104.47 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.
