Chemical Structure
Description
CEsium chloride:sodium chloride (2:1) (CsClNa) contains a salt form, 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.
CEsium chloride:sodium chloride (2:1) (CAS 15844-58-3) is a high-purity analytical reference standard with the molecular formula CsClNa and a molecular weight of 191.35 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
