Uses

Used in Agricultural Applications:
Ammonium 2,4-dichlorophenoxyacetate is used as a herbicide for controlling broadleaf weeds in various agricultural settings. It targets a wide range of weeds, such as dandelions, clover, and thistle, by mimicking the plant growth hormone auxin, leading to uncontrolled and abnormal plant growth and ultimately causing the weeds' death.
Used in Residential Applications:
Ammonium 2,4-dichlorophenoxyacetate is also used as a herbicide in residential settings to control unwanted broadleaf weeds in lawns and gardens. Its application helps maintain a clean and well-kept appearance by eliminating unwanted weeds.
However, it is important to note that ammonium 2,4-dichlorophenoxyacetate can be toxic to non-target plants and has been linked to potential environmental and health risks. As a result, there has been increased regulation and restrictions on its use in many countries to minimize these risks.

Structure, thermal stability and magnetic behavior of Mn(II) complexes with phenoxyacetic acid herbicides

The reaction of manganese(II) chloride with ammonium salt of 4-chloro-2-methylphenoxyacetic acid (MCPA), 2,4-dichlorophenoxyacetic acid (2,4-D) and 4-bromophenoxyacetic acid (4-Br) gave rise to the formation of hydrated complexes with formulas: Mn(MCPA)2·2H2O, Mn(2,4-D)2·2H2O and Mn(4-Br)2·3H2O. The compounds were characterized by elemental and thermal analyses, spectroscopic methods, as well as, by magnetic measurements. The complexes crystallize in monoclinic system. The Mn(II) ion is surrounded by oxygen atoms (from carboxylate groups and water molecules) in the octahedral arrangement. Variable-temperature (1.8–300 K) magnetic susceptibility measurements showed that compounds obey the Curie-Weiss law and have the paramagnetic properties. Being heated up to 1173 K the complexes decompose in three steps - first to anhydrous compounds: Mn(MCPA)2/Mn(2,4-D)2/Mn(4-Br)2 through intermediate products: MnO/Mn2OCl2/Mn2OBr2 to the following oxides: Mn2O3/Mn3O4/Mn3O4. The X-ray single crystal structure analysis was performed for Mn(II) complex with 4-bromophenoxyacetic acid after its recrystallization from N,N-dimethylformamide. The formation of hexanuclear cluster of manganese(II) carboxylate with a hydrophobic exterior was observed.
