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