Structural formula of 2,6-Dichlorobenzonitrile

2,6-Dichlorobenzonitrile

2,6-Dichlorobenzonitrile is an organic compound with the chemical formula C₇H₃Cl₂N. It is a derivative of benzonitrile and is characterized by the presence of two chlorine atoms at the 2 and 6 positions on the benzene ring.

Chemical Properties

2,6-Dichlorobenzonitrile is a nitrile, which means it contains a cyano group (_C_N) attached to an aromatic ring. The presence of chlorine atoms in the ortho positions relative to the nitrile group influences its chemical reactivity and physical properties.

Physical Properties

This compound is typically a white crystalline solid at room temperature. It has a melting point of approximately 146–148 °C and is sparingly soluble in water but more soluble in organic solvents such as acetone and ethanol.

Synthesis

2,6-Dichlorobenzonitrile can be synthesized through the chlorination of benzonitrile using chlorine gas in the presence of a catalyst. The reaction is typically carried out under controlled conditions to ensure selective chlorination at the 2 and 6 positions.

Applications

2,6-Dichlorobenzonitrile is primarily used as a herbicide. It is effective in controlling the growth of unwanted plants by inhibiting cell division. This compound is often used in agricultural settings to manage weed populations.

Safety and Handling

As with many chemical compounds, proper safety precautions should be taken when handling 2,6-Dichlorobenzonitrile. It is important to use appropriate personal protective equipment, such as gloves and goggles, and to work in a well-ventilated area. The compound should be stored in a cool, dry place away from incompatible substances.
