2,3, acid is an organic compound with the chemical formula C6H2Cl3NO2. The following is a description of its nature, use, preparation and safety information:
Nature:
2,3, acid is a colorless to light yellow crystal with a pungent odor. Its melting point is 135-137 degrees Celsius and boiling point is 361 degrees Celsius. The compound is insoluble in water and soluble in most organic solvents.
Use:
2,3, acid is an important intermediate compound, mainly used in pesticide and pharmaceutical fields. It can be used to synthesize many pesticides, such as herbicides and insecticides. In addition, it can also be used to prepare other organic compounds, such as pigments and light developers.
Preparation Method:
2,3, acid can be prepared by reacting 3,4-dichloropyridine and sodium cyanide under alkaline conditions. First, 3,4-dichloropyridine is reacted with sodium cyanide in the presence of aqueous ammonia to produce 3-cyanopyridine. The resulting product is then subjected to hydrolysis under acidic conditions to give 2,3, 3-acid.
Safety Information:
2,3, acid is irritating and should avoid contact with skin, eyes and mucous membranes. Wear appropriate protective equipment such as gloves and glasses during use.
