2hydroksibentsoehappo

2hydroksibentsoehappo, also known as salicylic acid, is an organic compound with the chemical formula C7H6O3. It is a beta-hydroxy acid (BHA) and a precursor to aspirin. Salicylic acid occurs naturally in the bark of willow trees and in other plants. It is a white crystalline solid that is sparingly soluble in water.

The compound is widely used in dermatology for its exfoliating and anti-inflammatory properties. It is a key ingredient in many over-the-counter acne treatments, shampoos for dandruff, and wart removers. Salicylic acid works by helping to shed dead skin cells and by opening clogged pores. Its anti-inflammatory action can also reduce redness and swelling associated with skin conditions.

In the chemical industry, salicylic acid serves as an important intermediate in the synthesis of various compounds, most notably acetylsalicylic acid (aspirin), a common pain reliever and fever reducer. It is also used in the production of dyes and perfumes. Historically, people have used willow bark, which contains salicylic acid, for medicinal purposes for centuries to relieve pain and reduce fever.
