溴化钠 Sodium Bromide

No.CAS 7647-15-6
An inorganic salt widely used across multiple industries. In chemical fields, it serves as a key raw material for manufacturing bromine‑related chemicals. It acts as a sedative in former medical applications to calm nerves. It works as an effective bromide source for photographic processing. It also functions in water treatment, oil‑well drilling fluids and textile dyeing. Besides, it can be applied in synthetic organic reactions as a bromine‑supplying reagent for synthesis purpose.
