[3396-11-0] C2H3CsO2 (MW 191.95) InChI = 1S/C2H4O2.Cs/c1-2(3)4;/h1H3,(H,3,4);/q;+1/p-1 InChIKey = ZOAIGCHJWKDIPJ-UHFFFAOYSA-M (reagent for alcohol inversion, coupling additive) Alternate Name: cesium acetate, acetic acid, cesium salt. Physical Data: 190–195 °C, d 2.423 g cm−3. Solubility: water soluble, very soluble in DMSO. Form Supplied in: white to off-white powder; readily available ≥99%. Analysis of Reagent Purity: titration by HClO4 ≥98.0%, trace metal analysis, atomic absorption. Preparative Methods: commercially available. Cesium acetate has been prepared by stirring a solution of cesium carbonate in dry methanol, followed by the addition of acetic acid. Methanol was removed after 1 h under reduced pressure to yield the desired product as a white solid.1 Purification: when synthesized from acetic acid, it can be purified by azeotropic distillation with dry toluene to remove excess acetic acid, and then dried under vacuum for 4–5 h.2 Handling, Storage, and Precautions: may be irritant to eyes, skin, and respiratory track, hygroscopic.
