How is the environmental fate of 2-Chlorobenzoic acid

2-Chlorobenzoic acid is a simple organic compound which can be used as a chemical building block. It is a kind of white crystals or powders withMolecular Formula: C7H5ClO2 andMolecular Weight: 156.57. It may be synthesized by the oxidation of 2-chlorotoluene with potassium permanganate.It can be synthesized by diazotization. It follows Sandmeyer reaction. It is irritant for the respiratory system and eyes. 

The CAS Registry Number of 2-Chlorobenzoic acid is 118-91-2. It is soluble in hot water,stable, combustible and incompatible with strong bases, strong oxidizing agents. We should store it in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.

2-Chlorobenzoic acid is mainly used as dyes, pesticides, pharmaceutical intermediates, for the manufacture of chlorpromazine, anti-inflammatory drugs such as Hope for adhesive and coating preservatives and synthesis of organic materials. It can be used to dye and color film, and also can be used as a fungicide.

2-Chlorobenzoic acid is an anthropogenic compound which may be released to the environment as a fugitive emission during its production, formulation or use as a perservative and chemical intermediate and may be formed and released during chlorination of wastewater. If released to soil, 2-Chlorobenzoic acid is expected to biodegrade under both aerobic and anaerobic conditions, although there may be a lengthy lag periods. It is not expected to significantly volatilize from either moist or dry soil to the atmosphere. 

2-Chlorobenzoic acid is expected to display moderate to high mobility in soil, and it will be found predominately in the dissociated form in moist soil under environmental conditions. If released to water, 2-Chlorobenzoic acid is expected to biodegrade under both aerobic and anaerobic conditions, although there may be a lengthy lag period. 

2-Chlorobenzoic acid(CAS NO: 118-91-2) may undergo direct photolytic degradation in water. It is not expected to significantly volatilize from water to the atmosphere, nor is it expected to significantly adsorb to sediment and suspended organic matter. 2-Chlorobenzoic acid will be found predominately in the dissociated form in water under the typical pH's found in the environment. 

If released to the atmosphere, 2-Chlorobenzoic acid may undergo a slow gas-phase reaction with photochemically produced hydroxyl radicals with an estimated half-life of 28.5 days. 2-Chlorobenzoic acid may also undergo atmospheric removal by wet deposition processes. Occupational exposure to 2-Chlorobenzoic acid may occur by dermal contact during its production, formulation or use. The general population may be exposed to 2-Chlorobenzoic acid by the ingestion of contaminated drinking water.
