7791-28-8 Usage

Uses

Used in Chemical Industry:
Barium bromide is used as a precursor to chemicals used in the manufacturing of bromides, photographic compounds, and phosphors. It is also used in the production of zinc bromide.
Used in Radiography:
Barium bromide dihydrate is used to purify radium, which is an important application in the field of radiography. It helps in obtaining high-purity radium, which is essential for various radiographic applications.
Used in Photography:
Barium bromide is used as a precursor to chemicals used in photography. It plays a crucial role in the development of photographic films and papers, as it helps in the formation of the light-sensitive emulsion layers.

Hazard

A poison.

Purification Methods

It crystallises from H2O (1mL/g) by partial evaporation in a desiccator. [Ehrlich in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 930 1963.]

Check Digit Verification of cas no

The CAS Registry Mumber 7791-28-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,9 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7791-28:
(6*7)+(5*7)+(4*9)+(3*1)+(2*2)+(1*8)=128
128 % 10 = 8
So 7791-28-8 is a valid CAS Registry Number.
