Usage

Uses

Used in Agricultural Industry:
Methanone, (2,4-dichlorophenyl)(4-hydroxyphenyl)is used as a key intermediate compound in the synthesis of herbicides for controlling specific weeds in rice fields. Specifically, it is utilized in the production of a herbicide compound that targets Echinochloa crus-galli, Scirpus hotarui, and Monochoria vaginalis. The application of Methanone, (2,4-dichlorophenyl)(4-hydroxyphenyl)- in herbicides helps improve the efficiency of weed control, leading to better crop yield and reduced competition for resources between the rice plants and the targeted weeds.

Synthesis and structure-activity relationships of benzophenone hydrazone derivatives with insecticidal activity

A broad range of benzophenone hydrazone derivatives was prepared and tested against selected chewing insect pests, allowing the analysis of structure-activity relationships. Good activity was found only when the aromatic rings were substituted at the 4-positions with an halogen atom and a triflate or perhaloalkoxy group. In contrast, a number of substituents on the hydrazone part led to active compounds, the best results being achieved with acyl-type substituents. The excellent laboratory and greenhouse activity of the best representatives was confirmed in semi-field trials against Spodoptera littoralis. ° 2001 Society of Chemical Industry.

Substituted aminoalkoxybenzene anti-fungicidal compositions and use

The compound of the formula STR1 wherein each of R1 and R2 individually is hydrogen, lower alkyl or lower alkenyl or together signify straight-chain alkylene with 2 to 4 carbon atoms, R3 is hydrogen, halogen or lower alkyl, Q is alkylene with 4 to 11 carbon atoms and at least 4 carbon atoms between the two free valencies or alkenylene with 4 to 11 carbon atoms and at least 4 carbon atoms between the two free valencies and each of Y and Y' individually is a direct bond or the group --CH2 --, --CH2 CH2 --, --CH=CH-- or --C C--, the group R1 R2 N--Q--O-- is attached to the 3- or 4 -position of ring A and the symbol R designates that the ring to which it is attached is unsubstituted or is substituted with at least one substitutent selected from the group consisting of halogen, trifluoromethyl, cyano, nitro, lower alkyl and lower alkoxy, and their pharmaceutically acceptable acid addition salts can be used for the control or prevention of fungal infections, especially of topical or systemic infections which are caused by pathogenic fungi, and for the manufacture of antifungally-active medicaments. The compounds of formula I have not only a pronounced antifungal activity, but they also exhibit synergistic effects in combination with other known antifungally-active substances which inhibit sterol biosynthesis such as ketoconazole and terbinafine.
