| Hazard Information | Back Directory | [Chemical Properties]
Colorless crystals, colored pink by
traces of iron. Very soluble in water. | [Application]
2-Hydroxy-5-sulfobenzoic acid (Sulfosalicylic acid) forms a dihydrate and is used in analytical chemistry to detect
albumins, iron, and mercury. Applications
described in patents include the use as a heat
stabilizer for polyacrylonitrile, as an additive used in the anodizing of metals,
and – as a tributyltin compound – as an agent for
the antibacterial protection of organic materials. The acid is also claimed to be suitable for a
pregnancy test for horses. | [Definition]
ChEBI: An arenesulfonic acid that is benzoic acid substituted by a hydroxy at position C-2 and a sulfo group at C-5. | [Production Methods]
Sulfosalicylic acid is obtained by heating one part of salicylic acid with 5 parts of concentrated sulfuric acid. It can also be prepared from the sulfochloride. | [Flammability and Explosibility]
