| Paraquat is a quartenary nitrogen herbicide widely used for broadleaf weed control. It is a quick acting, non-selective compound, that destroys green plant tissue on contact and by translocation within the plant. It is also used as a crop desiccant and defoliant, and as an aquatic herbicide. |

Apperance:Paraquat salts are colorless, white, or pale yellow crystalline solids, which are hygroscopic and odorless. The dichloride salt is stable except under alkaline conditions.
Stability:Paraquat is stable to heat when in acid or neutral solutions, but is hydrolyzed by alkali solutions. Paraquat decomposes at high temperatures to form toxic gases and vapors such as hydrogen chloride, nitrogen oxides, sulfur oxides, and carbon monoxide.
Solubility in water: very soluble (20 degrees C)
Solubility in solvents:
Paraquat has little to no solubility in organic solvents. The dichloride salt is sparingly soluble in lower alcohols and is insoluble in hydrocarbons.
Boiling point: 175
molecular weight :257.18
Relative density: (water = 1): 1.25
Solubility in water:g/100 ml at 20C: 70
Vapour pressure: Pa at 20C: <10
