1,3-Dichlorobenzene (also known asmeta-dichlorobenzene) is anaryl chloride and isomer ofdichlorobenzene with the formula C6H4Cl2. It is the least common of the three isomers of dichlorobenzene, and it is a colorless liquid that is insoluble in water. It is produced as a minor byproduct of thechlorination ofbenzene, but can also be prepared in a directed manner by theSandmeyer reaction of3-chloroaniline. It also arises from the isomerization of the other dichlorobenzenes at high temperature.[1]
This chemical is combustible. "Hazardous decomposition products" arecarbon monoxide,carbon dioxide, chlorine,hydrogen chloride gas. It is toxic to aquatic life with long-lasting effects.[2]
