Application
Cesium hydroxide solution is used to make porous cesium titanosilicates, potential ion-exchange materials for cleanup of radioactive wastes.[1]CsOH impregnated in FAU zeolites enhanced their basic properties without affecting the FAU framework.[2]It can effectively catalyse the condensation of methyl propionate with formaldehyde to yield methyl methacrylate.[3]

How does the storage temperature relate to shipping conditions?
1 answer-
The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment.

What is the molarity of Product 232041, Cesium hydroxide solution?
1 answer-
The molar concentration of Product 232041, Cesium hydroxide solution, is 5.7 M, based on a w/w% concentration of 50%, a density of 1.72 g/mL and a MW of 149.91. (50 g CsOH/100 g solution) X (1720 g solution/L solution) /(149.91 g CsOH/mole) = 5.7 moles/L.
