MECOPROP-P Chemical Properties,Uses,Production
Uses
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.
Flammability and Explosibility
Not classified
Mechanism of action
Selective, systemic, absorbed through leaves and translocated to roots. Synthetic auxin.
Synthesis
Starting from racemic α-chloropropionic acid, non-diastereomeric salts are formed with (1-naphthyl)ethylamine, a chiral amine. Stepwise crystallization is applied to resolve the salts to obtain (R)-α-chloropropionate. The salt is hydrolyzed with 3 mol/L aqueous sodium hydroxide solution to yield (R)-α-chloropropionic acid. Subsequently, this product undergoes a condensation reaction with 2-methyl-4-chlorophenol in an aqueous sodium hydroxide system at 90°C and a pressure of 0.25×10⁵ Pa for 25 hours, generating the salt of the target product. Finally, through acidification, extraction and recrystallization purification, Mecoprop-P with an optical purity of 95.9% and a yield of 97% is obtained.
