Synthesis

Pentachlorotoluene can be synthesized by chlorination of toluene.^[6][7]

Physical properties

This compound forms a white solid with a distinctive smell. The chlorine atoms contribute to its density, making it heavier than water. Because of its low volatility and fat-loving nature, pentachlorotoluene tends to build up in organic tissues, raising concerns in environmental and health research.^[8]

Uses

The compound is traditionally employed as an intermediate in the production of various chemicals, such as pesticides and pharmaceuticals. Nevertheless, because of its environmental persistence, tendency to bioaccumulate, and harmful effects on humans and wildlife, its usage has been significantly limited in numerous countries.^[8]
