Cesium is a highly reactive alkali metal; cesium and its salts (ionic compounds such as cesium chloride and cesium carbonate) are used in atomic clocks, medical imaging, and industrial catalysts due to their unique spectral properties and reactivity. Cesium metal (CAS 7440-46-2) has an atomic weight of 132.91 and is stored at ambient conditions. It carries a Danger signal word due to its extreme reactivity with water and air. Molekula supplies cesium salts from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
This substance is available from Molekula on enquiry. Full specification, Safety Data Sheet and Certificate of Analysis documentation are provided with your quotation once our team confirms the grade and pack size you need.
