7647-17-8 GNR9HML8BA Cesium chloride Caesium chloride Cesium chloride (CsCl) Cesium monochloride Dicesium dichloride EINECS 231-600-2 NSC 15198 Tricesium trichloride HSDB 7149 UNII-GNR9HML8BA EC 231-600-2 (CAS 7647-17-8) is a high-purity analytical reference standard with the molecular formula CsCl and a molecular weight of 168.36 g/mol.
The molecular framework of 7647-17-8 GNR9HML8BA Cesium chloride Caesium chloride Cesium chloride (CsCl) Cesium monochloride Dicesium dichloride EINECS 231-600-2 NSC 15198 Tricesium trichloride HSDB 7149 UNII-GNR9HML8BA EC 231-600-2 (CsCl) is characterized by chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
