A rapid and simple method for assay of nematicidal activity and its application to measuring the activities of dicarboxylic esters was written by Kimura, Yasuo;Mori, Masaaki;Hyeon, Suong-Be;Suzuki, Akinori;Mitsui, Yasushi. And the article was included in Agricultural and Biological Chemistry in 1981.Recommanded Product: malonic acid dibutyl ester This article mentions the following:
A method for nematocide bioassay is given, which differentiates between living and killed nematodes by letting the former descend from the incubation medium through a Japanese paper seal, followed by their count with a microscope. The method was applied to the study of the activity of dicarboxylic esters against the root nematode Pratylenchus coffeae. Of di-n-alkyl succinates tested, di-Pr succinate [925-15-5], di-Bu succinate [141-03-7], and diamyl succinate [645-69-2] were the most active. Branched alkyl succinates were less active. Six n-Bu esters of other dicarboxylic acids were also active, especially di-Bu glutarate [6624-57-3]. Since free acids and alcs. showed low activity, the ester linkage seems important. The preparation of the compounds is outlined. In the experiment, the researchers used many compounds, for example, malonic acid dibutyl ester (cas: 1190-39-2Recommanded Product: malonic acid dibutyl ester).
malonic acid dibutyl ester (cas: 1190-39-2) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
