Specification

The Cesium sulfate, with the CAS registry number 10294-54-9, is also known as Sulfuric acid, dicesium salt. It belongs to the product categories of Inorganics; Metal and Ceramic Science; Cesium Salts; CesiumMetal and Ceramic Science; Inorganic Salts; Salts; Synthetic Reagents; Analytical Reagents for General Use; C-D, Puriss p.a.; Puriss p.a.; Cesium; Cesium Biochemicals and Reagents; Salts of Alkali Metals; Alphabetical Synthetic Reagents; Biochemicals and Reagents; Density Gradient; Metal Sulfate. Its EINECS registry number is 233-662-6. This chemical's molecular formula is Cs₂O₄S and molecular weight is 361.87. What's more, both its IUPAC name and systematic name are the same which is called Dicesium sulfate. This chemical is the caesium salt of sulfuric acid. It is used to prepare dense aqueous solutions for use in isopycnic (or "density-gradient") centrifugation. In addition, it is used as analytical reagent and used for wine industry.

Physical properties about Cesium sulfate are: (1)ACD/LogP: -1.03; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): -5.53; (4)ACD/LogD (pH 7.4): -5.53; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1; (7)#H bond acceptors: 4; (8)#H bond donors: 2; (9)#Freely Rotating Bonds: 0; (10)Polar Surface Area: 82.98 Å²; (11)Enthalpy of Vaporization: 62.94 kJ/mol; (12)Boiling Point: 330 °C at 760 mmHg; (13)Vapour Pressure: 3.35E-05 mmHg at 25 °C.

Preparation of Cesium sulfate: this chemical can be prepared by Cesium carbonate with Sulfuric acid. This reaction needs solvent H₂O and other condition of heating.

Cs₂CO₃ + H₂SO₄ = CS₂SO₄ + CO₂ + H₂O
