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.

Potential Exposure

It is a chlorophenoxy-herbicide, used to control many broadleaf weeds. A derivative of phenoxy aryloxyalkanoic acid.

First aid

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seekmedical attention immediately. If this chemical contactsthe skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove fromexposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing hasstopped and CPR if heart action has stopped. Transferpromptly to a medical facility. When this chemical hasbeen swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

storage
