Sulfosalicylic acid solution 10% is widely used in medical and scientific laboratories. It is often used in urinalysis to detect proteins, as it forms a turbidity or precipitate with them. In histology, it is used to fix tissue specimens. In metallography, it is used as an etchant for microstructure analysis of metals and alloys.

Chemically, sulfosalicylic acid is a derivative of salicylic acid in which a hydroxyl group has been replaced by a sulfonic acid group. Its chemical formula is C7H6O6S. It is highly soluble in water and forms hydronium ions in aqueous solution, which leads to its acidic reaction.

The application of the sulfosalicylic acid solution 10% can lead to different results, depending on the specific application. For example, in urinalysis it can help diagnose kidney disease, while in metallography it helps reveal the microstructure of metals.
