The chemical formula for nicotine sulfate is C10H14N2·H2SO4. This compound is formed by combining nicotine, which is a naturally occurring alkaloid found in tobacco plants, with sulfuric acid (H2SO4) to create the sulfate salt. Nicotine sulfate is commonly used as an insecticide in agriculture to control pests such as aphids, caterpillars, and beetles. It works by disrupting the nervous systems of insects, leading to paralysis and eventual death. However, it's important to handle nicotine sulfate with extreme caution, as it is highly toxic to humans, animals, and the environment. Proper safety precautions and regulations should be followed when using this compound in agricultural settings.
