  • Patent number: 11591309
    Abstract: A method for manufacturing an insecticidal compound and insecticidal compositions comprising the insecticidal compound and methods of use are presented herein. The manufacturing method presented herein allows for a high purity grade of thiocyclam hydrochloride to be synthesized. The insecticidal compositions comprising the thiocyclam hydrochloride can be used for prevention of crop destruction by insects. The use of thiocyclam hydrochloride in insecticidal compositions as described herein can achieve greater efficacy than previously known insecticides, by eliminating the insect pests more reliably and efficiently.
    Type: Grant

  • Publication number: 20200352167
    Abstract: A flucarbazone sodium hemihydrate method and composition. A method of suppressing growth of grass and broadleaf weeds is described including applying to said weeds at least one dust-free composition comprising flucarbazone sodium-hemihydrate as an active ingredient. A method for preparing flucarbazone sodium-hemihydrate is also described including treating 4,5-dihydro-3-methoxy-4-methyl-5-oxo-N-[[2-(trifluoromethoxy)phenyl]sulfonyl]-1H-1,2,4-triazole-1-carboxamide (MSU) with aqueous sodium hydroxide under pH-controlled conditions; and confirming that a hemihydrate flucarbazone sodium has been obtained.
