Bromos

Bromos is a term occasionally used in chemistry to describe compounds that contain bromine as a substituent, counterion, or functional group. The most familiar example is the element bromine (Br). The term is not strictly standardized; in many cases "bromo-" is preferred for naming, while "bromos" may be used to refer collectively to bromine-containing species.

Inorganic bromos include bromides, salts of bromide such as sodium bromide (NaBr) and potassium bromide (KBr). They occur naturally in brines and have uses in photography history, medicine, catalysis, and as reagents in synthesis. Bromides can be produced by reacting bromine with metals or by neutralizing hydrobromic acid.

Organobromine compounds are a large group where bromine is bonded to carbon. They form by direct bromination with Br2, radical bromination, or conversion of other halides to bromides (for example, using N-bromosuccinimide). Common examples include bromoalkanes and aryl bromides; many participate in cross-coupling reactions such as Suzuki or Negishi.

Applications and concerns: Bromos find use in chemical synthesis, pharmaceuticals, dyes, and flame retardants. Some brominated compounds raise environmental and health concerns because of persistence and bioaccumulation, leading to regulation and substitution with safer alternatives in some cases.

Safety: Bromine and many brominated compounds are reactive and can be corrosive or toxic. Proper handling, ventilation, and waste management are important to minimize risk.
