Uses

Used in Herbicide Industry:
Methyl 4-aMino-3,6-dichloropicolinate is used as an intermediate in the synthesis of Arylex (A794890), a potent herbicide specifically designed for effective control of dicot weeds. Its role in the synthesis process is vital, as it contributes to the development of the herbicide's active ingredients, which target and inhibit key enzymes in the growth and development of dicotyledonous plants, thus providing an efficient and targeted weed control solution for agricultural applications.

Preparation method of fluoro-chloro-pyridine ester

To the method, 4 - amino -3 -6 -dichloropyridine 2 -2 - 6 -3 -4 -methyl formate is used as a raw material,2 - and amino protection is carried out through the method 4 -3 Coupling and deprotection steps give the above-described fluorochloropyrimidine, wherein the amino-protecting agent is a protecting agent sensitive to acidic conditions. The preparation method has the advantages of easily available raw materials, no need of special production equipment, more 70% or more reaction yield of each step, simple post-treatment and more than 99% product purity, and is more suitable for industrial production.

The discovery of Arylex active and Rinskor active: Two novel auxin herbicides

Multiple classes of commercially important auxin herbicides have been discovered since the 1940s including the aryloxyacetates (2,4-D, MCPA, dichlorprop, mecoprop, triclopyr, and fluroxypyr), the benzoates (dicamba), the quinoline-2-carboxylates (quinclorac and quinmerac), the pyrimidine-4-carboxylates (aminocyclopyrachlor), and the pyridine-2-carboxylates (picloram, clopyralid, and aminopyralid) In the last 10 years, two novel pyridine-2-carboxylate (or picolinate) herbicides were discovered at Dow AgroSciences This paper will describe the structure activity relationship study that led to the discovery of the 6-aryl-picolinate herbicides Arylex active (2005) and Rinskor active (2010) While Arylex was developed primarily for use in cereal crops and Rinskor is still in development primarily for use in rice crops, both herbicides will also be utilized in additional crops.

4-aminopicolinates and their use as herbicides

4-Aminopicolinic acids, having halogen, alkoxy, alkylthio, aryloxy, heteroaryloxy or trifluoromethyl substituents in the 3-, 5- and 6-positions, and their amine and acid derivatives are potent herbicides demonstrating a broad spectrum of weed control.
