MCPB Usage And Synthesis

Chemical Properties

Colorless crystal; melts at 100 °C (212 °F);practically insoluble in water (44 mg/L at25 °C/77 °F); readily dissolves in most organicsolvents.

Uses

MCPB is used for research regarding herbicides to control weed in crop field.

Uses

Herbicide.

Definition

ChEBI: A monocarboxylic acid that is butyric acid substituted by a 2-methyl-4-chlorophenoxy group at position 4.

Hazard

Toxic by ingestion.

Health Hazard

MCPB is structurally similar to 2,4-DB,except one methyl group substituting a Clatom in the ring. Toxic properties and thesymptoms are similar to 2,4-DB. It is mod-erately toxic by ingestion and possibly otherroutes of exposure. Skin contact can causeirritation.
LD50 oral (rat): 680 mg/kg
LD50 oral (mouse): 800 mg/kg.

Agricultural Uses

Herbicide: A metabolite of MCPA (see above). MCPB is a phenoxy herbicide produced as a sodium salt and an acid. Herbicide registered for use on peas prior to flowering. There are no residential uses of MCBP. Target organisms: post-emergence control of Canadian thistle, buttercup, mustard, purslane, ragweed, common lambsquarters, pigweed, smartweed, sowthistle, morning glory and other broad leaf weeds[83] .
