| Hazard Information | Back Directory | [Hazard]
Moderately toxic by ingestion and skin contact. | [Description]
Flamprop-M-isopropyl is synthesized from 3-chloro-4-fluoroaniline, benzoyl chloride and methyl S-2-chloro propionate. This compound is used as selective grass herbicide in wheat and barley.
| [Production Methods]
The commercial production of flamprop-M-isopropyl involves the synthesis of a stereospecific ester derived from L-alanine, ensuring herbicidal selectivity and potency. The process begins with the preparation of N-benzoyl-N-(3-chloro-4-fluorophenyl)-L-alanine, which is then esterified using isopropyl alcohol under controlled conditions to yield the desired isopropyl ester. This reaction typically requires acid catalysis and precise temperature regulation to maintain the integrity of the chiral centre. | [Mechanism of action]
Selective, systemic, absorbed by leaves. Thought to inhibit cell elongation. | [Pesticide Type]
