Chemical Properties
Off-White Solid
Chemical Properties
Mecoprop is a colorless, crystalline solid. Odorless.
Uses
Herbicide.
Definition
ChEBI: 2-(4-chloro-2-methylphenoxy)propanoic acid is a monocarboxylic acid that is lactic acid in which the hydroxyl hydrogen is replaced by a 4-chloro-2-methylphenyl group. It is an aromatic ether, a monocarboxylic acid and a member of monochlorobenzenes. It is functionally related to a rac-lactic acid.
General Description
Colorless crystals. Corrosive to metals. Used as an herbicide.
Air & Water Reactions
Soluble in water.
Reactivity Profile
A phenoxy aryloxyalkanoic acid derivative.
Hazard
Toxic by ingestion and inhalation, irritant to skin and eyes.
Agricultural Uses
Herbicide: A General Use Pesticide, postemergent herbicide, most often used in combination with other pesticides. Most of the production is used on turf, including lawns, sport turf and commercial sod production for control of creeping broadleaf weeds such as clovers, chickweed, ivy, plantain and similar plants. It is also used on wheat, barley and oats. A small percentage is used in noncrop areas such as rights-of-way, drainage ditch banks and forest site preparation.
