It can also be synthesized in the laboratory. To do so, sodium hydroxide and bromine are added to an ice-water solution of succinimide. The NBS product precipitates and can be collected by filtration. Crude NBS gives better yield in the Wohl-Ziegler reaction. In other cases, impure NBS (...

Chlorine and bromine are both effective sanitizers, but each one has its own optimal working conditions, and its own pros and cons. Advantages of Chlorine Typically half the cost of bromine sanitizers. Compatibility with Cyanuric Acid (stabilizer/conditioner) protects it against UV evaporation. ...
