Sulfosalicylic acid

From WikiMD's Wellness Encyclopedia

Sulfosalicylic acid is a type of organic compound that is often used in urine tests for protein detection. It is a white, crystalline solid that is soluble in water, alcohol, and ether.

Chemical Properties[edit | edit source]

Sulfosalicylic acid, also known as 5-sulphosalicylic acid or SSA, is an organic acid with the chemical formula C7H6O6S. It is a derivative of salicylic acid, with a sulfonic acid group replacing one of the hydroxyl groups. This gives it strong acidic properties, making it a useful reagent in various chemical reactions.

Uses[edit | edit source]

One of the primary uses of sulfosalicylic acid is in the detection of proteins in urine, a test often used in the diagnosis of kidney disease. The acid reacts with the proteins to form a precipitate, which can then be measured to determine the protein concentration.

In addition to its medical uses, sulfosalicylic acid is also used in the dye industry. It acts as a mordant, a substance that helps the dye bind to the fabric, improving the colorfastness of the dye.

Safety[edit | edit source]

Like many acids, sulfosalicylic acid can cause burns if it comes into contact with the skin or eyes. It is also harmful if swallowed or inhaled. Therefore, it should be handled with care, using appropriate personal protective equipment.
