Chemical Properties
Colorless crystals, colored pink by
traces of iron. Very soluble in water.
Uses
Reagent for albumin, colorimetric reagent for
ferric ion, intermediate for dyes, surfactants, catalysts,
grease additives.
Uses
Sulfosalicylic Acid is a benzoic acid derivative with acetylcholinesterase inhibitory properties.
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.
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.
