What is MECOPROP?

Chemical properties

Mecoprop is a colorless, crystalline solid. Odorless.

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.

Potential Exposure

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

Shipping

UN3345 Phenoxyacetic acid derivative pesticide, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials

Incompatibilities

Mecoprop is a weak acid. Incompatible with strong bases and oxidizers.

Waste Disposal

In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
