CH3CHClCOOH

CH3CHClCOOH, also known as chloroacetic acid, is an organic compound with the molecular formula C3H5ClO2. It is a derivative of acetic acid, where one hydrogen atom has been replaced by a chlorine atom. Chloroacetic acid is a colorless liquid with a pungent odor, and it is soluble in water and many organic solvents.

Chloroacetic acid is primarily used as a building block in the synthesis of various chemicals, including pharmaceuticals, agrochemicals, and dyes. It is also used in the production of certain polymers and resins. In the pharmaceutical industry, chloroacetic acid is used as a precursor in the synthesis of drugs such as chloroquine, an antimalarial medication.

Chloroacetic acid is a weak acid, with a pKa value of approximately 2.86. It can react with bases to form salts, such as chloroacetate salts. These salts are used in various applications, including as a chelating agent in metalworking fluids and as a pH buffer in cosmetics and personal care products.

Despite its widespread use, chloroacetic acid can be harmful if ingested or inhaled. It can cause irritation to the skin, eyes, and respiratory tract, and prolonged exposure can lead to more serious health effects, including liver and kidney damage. Therefore, it is important to handle chloroacetic acid with care and to follow proper safety procedures when working with it.
