Application field

1. The photosensitive industry is used to prepare film photosensitive liquid.

2. It is used in medicine to produce diuretics and tranquilizers, and to treat neurasthenia, neurological insomnia, mental excitement, etc. Sedatives dissociate bromide ions in the body, have a mild inhibitory effect on the central nervous system, and can calm agitated chickens. Oral administration is easy to absorb but slow to excrete. It is used to relieve the stress caused by factors such as transfer, beak cutting, drug injection, immunization, capture, blood sampling or drug poisoning.

3. Used in the production of synthetic fragrances in the fragrance industry.

4. Used as brominating agent in printing and dyeing industry.

5. It is also used for trace determination of cadmium, preparation of detergent for automatic dish washer, production of bromide, organic synthesis, photographic paper plates, etc.
