Dichlorophenol

The dichlorophenols (DCP) are a group of aromatic compounds from the group of chlorine, phenols, which are derived from both the phenol and the chlorobenzene and the dichlorobenzenes. The structure consists of a benzene ring with an added hydroxy (-OH) and two chlorine atoms ( Cl ) as a substituent. Due to their different arrangement resulting six constitutional isomers. You have the molecular formula C6H4Cl2O, a molar mass of 163.00 g / mol and are as colorless crystalline needles before. In their production under unfavorable conditions arise as a byproduct of polychlorinated dibenzodioxins and dibenzofurans. In particular, the 2,4-dichlorophenol is used as herbicide use.

Properties

Use

2,4-dichlorophenol is used as an antifungal agent in stockings, shoe inserts, etc., and also for the manufacture of herbicides, such as 2,4-dichlorophenoxyacetic acid, which accounted for half of the employed in the Vietnam War defoliant Agent Orange, 2,4- dichlorophenoxypropionic and used in moth-proofing agents. 3,5-dichlorophenol is used in some standardized bioassay method for water as the luminescent bacteria test as a reference substance.

Biological Significance

2,6- dichlorophenol is used by the females of 14 species of ticks as a pheromone. The isomeric 2,4-dichlorophenol on the other hand is a herbicide and is, however, also produced by the penicillin mold growth as Homon.
