Uses

2,3,5,6-Tetrachloroterephthalic Acid is a pest control chemical and plant growth regulator.

Definition

ChEBI: Chlorthal is a 2-hydroxyisophthalic acid.

Production Methods

Chlorthal is made through the established phthalate-based synthesis in which the tetrachlorinated aromatic core is constructed and then converted to the corresponding acid chloride.

Agricultural Uses
