Imazamethabenz is a herbicide. Imazamethabenz-methyl is used on cereals and sunflowers, especially against wild oat. Activity and selectivity are due to differential de-esterification to the active parent acid in target and crop species.
13C15-Nivalenol is intended for use as an internal standard for the quantification of nivalenol by GC- or LC-MS. Nivalenol (T13797) is a trichothecene mycotoxin that has been found inFusarium.1It is lethal to mice (LD50= 6.9 mg/kg).2Nivalenol (5,10,and 15 mg/kg)also induces thymic,splenic,and Peyer's patch cell apoptosis in mice.3
HT-2 Toxin-13C22 is intended for use as an internal standard for the quantification of HT-2 toxin by GC- or LC-MS. HT-2 toxin is a type A trichothecene mycotoxin and an active,deacetylated metabolite of the trichothecene mycotoxin T-2 toxin .1,2Like T-2 toxin,HT-2 toxin inhibits protein synthesis and cell proliferation in plants.2HT-2 toxin also reduces viability of HepG2,A549,HEp-2,Caco-2,A-204,U937,Jurkat,and RPMI-8226 cancer cells with IC50values ranging from 3.1 to 23 ng/ml and human umbilical vein endothelial cells with an IC50value of 56.4 ng/ml.1It induces oxidative stress,DNA damage,and autophagy in,as well as halts the development of,cultured mouse embryos when used at a concentration of 10 nM.3HT-2 toxin has been found in cereal grains and food products.4,5
Clodinafop-propargyl (Standard) is the standard substance of Clodinafop-propargyl, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Clodinafop-propargyl, a prominent member of aryloxyphenoxy-propionate herbicides, is employed for postemergence management of annual grasses in cereals, such as Avena, Lolium, Setaria, Phalaris, and Alopecurus spp.
