Cesium Deuteroxide (CsOD) Supplier
Cesium deuteroxide — CsOD, also written caesium deuteroxide — is the deuterated analogue of cesium hydroxide and the strongest of the common alkali-metal deuteroxide bases. It is supplied as a solution in deuterium oxide (D2O) for applications that need maximum base strength without introducing exchangeable protons.
Like rubidium deuteroxide, CsOD has no reliable mainstream commercial source. BSI produces cesium deuteroxide to order in the United States at customer-specified concentration and isotopic purity, characterized through our Texas Tech University and CEES relationships. It ships as a low-friction Class 8 solution. Orders are quote-based and shipped within the United States only.
Applications
What Cesium Deuteroxide Is Used For
Strong-Base Chemistry
As the strongest common alkali deuteroxide, CsOD is chosen where maximum base strength in a deuterated medium drives the reaction.
H/D Exchange Chemistry
A cesium-cation deuteroxide base for base-catalyzed hydrogen/deuterium exchange without adding exchangeable protons.
Specialty Isotope Research
Cesium-specific isotope-labeling and cation-dependent studies where a lighter alkali deuteroxide is not suitable.
Questions
Cesium Deuteroxide FAQ
What is cesium deuteroxide used for?
CsOD is the strongest of the common alkali-metal deuteroxide bases, used in specialty isotope research and strong-base H/D exchange chemistry, typically supplied as a solution in D2O.
Is cesium deuteroxide the same as caesium deuteroxide?
Yes. Cesium deuteroxide and caesium deuteroxide are the same compound, CsOD — the two spellings are US and international variants of the element name.
Where can I buy cesium deuteroxide?
CsOD has no reliable mainstream commercial source. BSI produces it to order in the US and supplies it as a D2O solution at customer-specified concentration, quote-based.
Does BSI ship cesium deuteroxide internationally?
No. BSI sells to US destinations only. Every order requires a US ship-to address and a lawful US end-use confirmation.
