CAS: 84-87-7

1-Naphthol-4-sulfonic acid is a compound that is used as an analytical reagent. It can be synthesized by heating 1-naphthol with concentrated sulfuric acid in the presence of a polymerization initiator. The reaction produces 1,4-dioxane, which is then converted to 1-naphthol-4-sulfonic acid by hydrolysis with deionized water and hydrochloric acid. The analytical reagent has been used for the analysis of impurities in polymers, such as trifluoroacetic acid, and for wastewater treatment. Radiation causes the release of light emission from 1-naphthol-4-sulfonic acid, making it useful for determining the level of nitrite ion in wastewater. This chemical has also been found to react with sulfamate ions to produce structural formula (SO2)2NH3.
