Product Description: Sodium Bromide is white cubic crystal or white granular powder with slightly bitter taste. It is easily soluble in water and glycerol, slightly soluble in ethanol. It has strong hygroscopicity and is easy to agglomerate when exposed to air; its aqueous solution is neutral or weakly alkaline. The product is divided into three grades: Industrial Grade, Photographic Grade and Pharmaceutical Grade. Produced by synthetic refining process, featuring high purity, trace impurities, clear solution and stable batch indicators. Widely used in oilfield drilling, photosensitive film materials, pharmaceutical intermediates, bromide chemical synthesis and printing & dyeing auxiliaries. Complete COA and MSDS documents can be provided. It is ordinary non-dangerous chemical, fully compliant with global customs clearance standards for import and export.
