Calcium bromide hydrate
Calcium bromide hydrate (CAS 71626-99-8) is a hydrated salt of calcium and bromine with the linear formula CaBr₂ · xH₂O. Available as a Vetec™ reagent grade, this compound typically presents as an assay of 84%. It is a key chemical intermediate used in various industrial applications, notably in the oil and gas sector for completion fluids.

Completion Fluids in Oil and Gas
Calcium bromide hydrate is extensively used as a component in high-density, solids-free completion fluids and workover fluids in the oil and gas industry. Its high density helps to control formation pressures during well completion and intervention operations.
Chemical Intermediate
As a source of bromide ions and calcium ions, calcium bromide hydrate serves as an intermediate in the synthesis of other chemical compounds. It is utilised in processes requiring these specific ionic species.
Water Treatment
In certain water treatment applications, calcium bromide may be employed. Its properties can be beneficial in specific formulations aimed at managing water quality, although its use is less common than in oilfield applications.
