Sodium bromide

Sodium bromide is an inorganic compound with the chemical formula NaBr. It is a colorless cubic crystal or white granular powder, odorless, with a salty and slightly bitter taste. Sodium bromide easily absorbs moisture in the air and clumps, but does not deliquescence. Sodium bromide is easily soluble in water and the aqueous solution is neutral. Sodium bromide is slightly soluble in alcohol and can react with dilute sulfuric acid to produce hydrogen bromide. Under acidic conditions, sodium bromide can be oxidized and free of bromine. Sodium bromide can be used in industries such as photosensitive industry, spice industry, printing and dyeing industry, as well as for trace determination of cadmium, manufacturing of bromide, inorganic and organic synthesis, photographic paper plate, etc.

Application

1. The photosensitive industry is used to prepare film photosensitive liquids, in medicine to produce diuretics and sedatives, in the fragrance industry to produce synthetic fragrances, and in the printing and dyeing industry to use as brominating agents. In addition, it is also used in organic synthesis and other fields.

2. Microdetermination of cadmium, production of bromide, inorganic and organic synthesis, photographic plates, pharmaceuticals.

3. Used in the pharmaceutical industry as diuretics and sedatives. Used to treat neurasthenia, neurogenic insomnia, and mental excitement.

4. Used for preparing photosensitive film with photosensitive liquid. Used in the pharmaceutical industry as diuretics and sedatives. It is also used in the synthetic spice, pharmaceutical, and dye industries, as well as in the formulation of detergents for automatic dishwashers.

Quality standard

According to the standards of the People's Republic of China, the chemical reagent sodium bromide is tested according to the GB 1265-77 standard.

Health hazards

1. Toxicological data

Acute toxicity (LD50): 7000mg/kg (orally administered to rats); 3500mg/kg (rabbit transdermal).

To prevent ingestion, inhalation, and contact with eyes and skin.

2. Ecological data

Water hazard level 1: It is slightly harmful to water. Do not let undiluted or large amounts of products come into contact with groundwater, waterways, or sewage systems.

First aid measures

To prevent ingestion, inhalation, and contact with eyes and skin. If ingested or inhaled, dizziness, nausea, and vomiting may occur. Seek medical attention immediately. If splashed into the eyes, immediately rinse with fresh water for 20 minutes; If the skin comes into contact with sodium bromide, rinse with plenty of water.

Storage and transportation

1. It should be stored in a dry, cool, and well ventilated place. To prevent direct sunlight exposure, isolate from flames and heat sources, and avoid co storage and mixing with ammonia, oxygen, phosphorus, antimony powder, and alkalis. Keep away from wood chips, shavings, straw, etc. to prevent combustion.

2. When a fire occurs, sand and carbon dioxide fire extinguishers can be used to extinguish it.

Note: The product can be customized according to customer needs.
