Armstrong's acid (naphthalene-1,5-disulfonic acid) is a fluorescent organic compound with the formula C 10 H 6 (SO 3 H) 2. It is one of several isomers of naphthalenedisulfonic acid. It a colorless solid, typically obtained as the tetrahydrate. Like other sulfonic acids, it is a strong acid.
Sulfonic acid is a compound with general formula RSO 2 OH, where R is an aliphatic or aromatic hydrocarbon. It is a derivative of sulfuric acid (HOSO 2 OH) where an OH has been replaced by a carbon group or a compound where a hydrogen atom has been replaced by treatment with sulfuric acid; for example, benzene is converted to benzenesulfonic ...

Naphthalene-1-sulfonic acid undergoes many reactions, some of which are or were of commercial interest. Upon heating with dilute aqueous acid, it reverts to naphthalene. Fusion with sodium hydroxide followed by acidification gives 1-naphthol. Further sulfonation gives 1,5-naphthalene-disulfonic acid.
