CAS NO : 37248-47-8 EC NO : MF : C20H35NO13 MW : 497.4908 Product description : Chemical Name:N-[(1S)-(1, 4, 6/5)-3-hydroxymethyl-4, 5, 6-trihydroxy-2-cyclohexemyl] [O-β-D-glucopyranosyl-(1--3)] Solacol; Validacin; validamycin;Molecular Formula:C20H35NO13Molecular Weight:497.5Properties:Validamycin is a agricultural antibiotic. All its molecules contain glucose. Its solution is brownish transparent liquid, and the technical product is a color-less and odorless hygroscopic powder, soluble in water, dimethyl formamide, insoluble in ethyl acetate, ethyl ether and petroleum ether. Under the normal room temperature, it is stable in 3-9 aquatic medium, positive reaction with anthraquinone, phenol-sulfuric acid, Fehling reagent and alkaline KMnO4 solution. It can be mixed with many pesticides in uses.Application:Validamycin is a kind of agricultural antibiotic with good control on disease of fungi such as sheath blight of rice, wheat and corn without pollution to environment. It is a water soluble antibiotics produced by Strep. Hygroscopicus Var. Jinggangensis Yen, which consists of six components named A, B, C, D, E, F respectively. Validamycin A is the major active ingredient. Validamycin is a systemic antibiotics for agriculture use to control rice sheath blight, wheat sheath blight and rice false smut. It can be absorbed by the cells of the pathogeny fungus as nutrition and transmitted through the hyphae, whose growth are affect when contacting with the active ingredient, which make the hyphal top abnormal and inhibit the growth of the hyphae through inhibiting the synthesis of inositol which is the essential for the growth of fungi.Specifications:60% Validamycin A technical powder (TC)
