Salicylic acid CAS 69-72-7

Description of Salicylic acid

Salicylic acid (from Latin salix, willow tree) is a monohydroxybenzoic acid, a type of phenolic acid and a beta hydroxy acid. It has the formula C7H6O3. This colorless crystalline organic acid is widely used in organic synthesis and functions as a plant hormone. It is derived from the metabolism of salicin. In addition to serving as an important active metabolite of aspirin (acetylsalicylic acid), which acts in part as a prodrug to salicylic acid, it is probably best known for its use as a key ingredient in topical anti-acne products. The salts and esters of salicylic acid are known as salicylates. The medicinal part of the plant is the inner bark.
It is on the WHO Model List of Essential Medicines, the most important medications needed in a basic health system.
