Anilinium chloride is the organic compound with the formula C6H5NH+3Cl. A white solid, it is the chloride salt of anilinium, which is the conjugate acid of aniline, C6H5NH2. Anilinium chloride is produced by treatment of aniline with hydrochloric acid. The cation consists of a phenyl ring attached to a tetrahedral ammonium center. The C-N bond elongates from 1.41 Å in aniline to 1.474 Å in anilinium.[2]
