Ammonium bromide, NH 4 Br, is the ammonium salt of hydrobromic acid. The chemical crystallizes in colorless prisms, possessing a saline taste; it sublimes on heating and is easily soluble in water. On exposure to air it gradually assumes a yellow color because of the oxidation of bromide (Br − ) to bromine (Br 2 ).

Cetrimonium bromide, also known with the abbreviation CTAB, is a quaternary ammonium surfactant with a condensed structural formula [(C 16 H 33)N(CH 3) 3]Br. It is one of the components of the topical antiseptic cetrimide. [1] The cetrimonium (hexadecyltrimethylammonium) cation is an effective antiseptic agent against bacteria and fungi.
A bromide ion is the negatively charged form (Br −) of the element bromine, a member of the halogens group on the periodic table.Most bromides are colorless. Bromides have many practical roles, being found in anticonvulsants, flame-retardant materials, and cell stains. [3]
Ammonium is a modified form of ammonia that has an extra hydrogen atom. It is a positively charged molecular ion with the chemical formula NH + 4 or [NH 4] +. It is formed by the addition of a proton (a hydrogen nucleus) to ammonia (NH 3).
* Ammonium nitrate is an industrial chemical commonly used in fertilizers and as an explosive for quarrying and mining. * A large quantity of ammonium nitrate exposed to intense heat can explode.
Quaternary ammonium cation. The R groups may be the same or different alkyl or aryl groups. Also, the R groups may be connected. In organic chemistry, quaternary ammonium cations, also known as quats, are positively-charged polyatomic ions of the structure [NR 4] +, where R is an alkyl group, an aryl group [1] or organyl group.
