Usage

Uses

Used in Agricultural Industry:
(2,4,5-Trichlorophenoxy)acetic acid was used as a herbicide for controlling broadleaf weeds in various agricultural settings. Its application was aimed at improving crop yields by reducing competition from unwanted plant species.
Used in Military Applications:
During the Vietnam War, 2,4,5-T was one of the components of Agent Orange, a herbicide used for defoliation purposes to clear dense vegetation and expose enemy positions. Its use in this context was intended to provide tactical advantages in the conflict.
Despite its ban, the long-lasting environmental impacts of (2,4,5-Trichlorophenoxy)acetic acid persist, as it can remain in the soil and water for extended periods, posing ongoing risks to ecosystems and human health.

Synthesis, Structure, and Properties of the 2-[5-(Aryloxyacetyl)-Amino-1,3,4-Thiadiazol-2-Ylthio] Propionate Derivatives

A series of novel 2-[5-(aryloxyacetyl)-amino-1,3,4-thiadiazol-2-ylthio] propionate derivatives were synthesized in high yield, and their structures were characterized by IR, 1H NMR, 13C NMR, and elemental analysis, coupled with one selected single-crystal X-ray structure determination. The herbicidal activities of target compounds were assessed. The preliminary bioassay results showed that some compounds exhibited moderate to strong herbicidal symptoms in preemergence and postemergence tests. At 150 g/ha, S. tritici. show tolerance, while E. crus-galli L., E. Dahuricus, A. retroflexus, and C. glaucum L. were killed or severely injured. The activity of some compounds was comparable to the commercial herbicide 2,4-D. A suitable electron-withdrawing substituent at the 2-and/or 4-position of the phenyl ring was essential for high herbicidal activity. Moreover, the antifungal activities of the compounds have also been studied. The compounds were found to possess broad-spectrum antifungal activity.

Treatment of skin conditions by use of PPAR alpha activators

Disorders of the skin and mucous membrane that have a disrupted or dysfunctional epidermal barrier are treated or prevented by topical application of compounds that are either activators of the farnesoid X receptor, activators of the peroxisome proliferator-activated receptor alpha , and oxysterol activators of the LXR alpha receptor. The same compounds are also effective in treating disorders of epidermal differentiation and proliferation.

Soluble polymer based matrix for chemically active water insoluble components

This invention relates to a water soluble matrix composition comprising an anionic surfactant, a C6 to C18 alkyl pyrrolidone, urea and a water insoluble copolymer of vinyl pyrrolidone with not more than 50 wt. % of a comonomer selected from the group of an α-olefin, vinyl acetate, an acrylic or methacrylic acid ester and methacrylamide as a free flowing particulate solid which matrix is suitably mixed with a water insoluble, chemically active component, such as an agrochemical, to provide a clear sprayable film forming emulsion, such as a non-leachable film on a plant or other substrate surface. The invention also relates to the method of preparing the matrix and to the incorporation of an agrochemical concentrate and plant spray composition.

Trichlorophenoxy alkanoic acid free of chlorinated dibenzo-p-dioxins

This invention provides as new compositions of matter 2,4,5-trichlorophenoxy acetic acid (2,4,5-T) and (2-2,4,5-trichlorophenoxy) propionic acid (Silvex) including the hydrolyzable salts, aliphatic esters and amides of these acids, which compositions are free of chlorinated dibenzo-p-dioxins.

Pesticide-polymer systems prepared from vinyl monomers

Controlled release pesticide-polymer systems are prepared by the polymerization of vinyl monomers containing pendant pesticides. The vinyl monomers are prepared by reacting an acrylic acid derivative with a pesticide or a pesticide derivative having an active hydrogen. The pesticide-polymer systems prepared from the pesticide vinyl monomers release the active pesticide material by hydrolysis or chemical depolymerization under conditions of use.
