CClCOOH

CClCOOH, also known as trichloroacetic acid, is a chlorinated derivative of acetic acid. Its chemical formula is CCl3COOH. It is a strong acid, with a pKa of 0.65. Trichloroacetic acid is a white crystalline solid that is soluble in water and alcohol. It is a corrosive substance and can cause burns on contact with skin and eyes.

Trichloroacetic acid is used in a variety of applications. It is commonly used as a chemical peel in dermatology to remove dead skin cells and improve the appearance of acne scars and wrinkles. In biochemistry, it is used as a precipitating agent for proteins. It is also used as a reagent in organic synthesis. In laboratory settings, it can be used as a solvent for certain reactions.

Industrially, trichloroacetic acid has been used as a herbicide, although its use for this purpose has declined due to environmental concerns. It can be produced through the chlorination of acetic acid or chloroacetic acid. Due to its corrosive nature, proper handling procedures and personal protective equipment are essential when working with trichloroacetic acid. It is important to store it in a cool, dry place away from incompatible materials.
