溴化鈉Sodium Bromide
Molecular formula:NaBr Molecular weight:102.8938
Application:It is used as a diuretic or sedative in medicine and has a role in strengthening the inhibition process of the cerebral cortex. It is used as a brominating agent in industries such as synthetic fragrances, pharmaceuticals and dyes, and also as a chemical reagent and photographic industry.
Property:Colorless cubic crystal or white granular powder, belonging to the equiaxed crystal system, odorless, salty and slightly bitter. It absorbs moisture in the air and agglomerates, but it does not deliquesce. The specific gravity is 3.203 (25 ℃), the melting point is 747 ℃, the boiling point is 1390 ℃, soluble in water, slightly soluble in alcohol, and its aqueous solution is neutral and conductive.
CAS #: 7647-15-6 HS : 2827510000 drawback:0%
