2-Chlorobenzoic acid, also known as o-chlorobenzoic acid, is a white crystalline solid with the molecular formula C7H5ClO2. It is a colorless to white solid with a melting point of 135-137 °C. It is soluble in organic solvents such as ethanol, acetone, and dichloromethane.
2-Chlorobenzoic acid is an important intermediate used in the production of pharmaceuticals, dyes, and other organic chemical compounds. It is used as a starting material for the synthesis of many compounds, including lignin, lignans, and plant hormones. It is also used as a reagent in the preparation of chloroacetamides, sulfonamides, and carboxylic acid derivatives.
2-Chlorobenzoic acid is widely used in the manufacture of pharmaceuticals, dyes, and other organic chemical compounds. It is used as a catalyst in the production of pharmaceuticals such as antibiotics, antifungal agents, and anti-inflammatory drugs. Additionally, it is used as a preservative in food and beverages.
2-Chlorobenzoic acid is toxic if inhaled or ingested. It is corrosive to the eyes, skin, and respiratory tract. If exposed to the skin, it may cause irritation and dermatitis. Inhalation may cause irritation to the upper respiratory tract, coughing, and difficulty breathing. If ingested, it may cause nausea, vomiting, abdominal pain, and diarrhea.
2-Chlorobenzoic acid should be handled with care and stored in a cool, dry place in a tightly sealed container. It should be kept away from heat, sparks, and open flames. It should also be kept away from strong oxidizing agents such as nitric acid, chlorine, and sodium hypochlorite.
