What is MECOPROP-P?
The Uses of MECOPROP-P
Mecoprop-P has been used as a reference standard for identification of mecoprop enantiomer elution using chiral GC columns. It has also been used as a pesticide in a comparative study to detect the pesticide contamination of indoor air and human hair samples.
Definition
ChEBI: The (R)-enantiomer of 2-(4-chloro-2-methylphenoxy)propanoic acid; the active stereoisomer of the racemic herbicide mecoprop.
General Description
Mecoprop-P, a phenoxyalkanoic acid is widely used as herbicide. It forms colourless and odourless crystals. The (R)-isomer of mecoprop is the active herbicide site. It is generally used for postemergence control of broad-leaved weeds by translocating the herbicide to the roots.
