[Uses]

Flamprop-methyl is a post-emergence herbicide usually used on wild oats.
[Production Methods]

Commercial information on flamprop methyl is sparse, but the core industrial route can be inferred from its documented chemical structure and typical amide forming practices. Flamprop methyl is the methyl ester of flamprop, so production begins with synthesis of the parent acid which is formed by acylating 3 chloro 4 fluoroaniline with benzoyl chloride, then coupling the resulting benzamide with a suitable alanine derivative under controlled conditions to build the substituted propanoic acid backbone. The acid is then esterified with methanol, usually via acid catalysed or thionyl chloride mediated esterification, to yield flamprop methyl, followed by purification, solvent removal, and milling to produce the technical active ingredient.
[Mechanism of action]

Selective, systemic, absorbed by leaves. Works by disrupting microtubules in sensitive plants, leading to inhibited cell division and elongation, and ultimately stunted growth
