Benomyl-d4 (benzimidazole-4,5,6,7-d4)

Benomyl-d4, also known as benzimidazole-4,5,6,7-d4, is a deuterated version of the fungicide Benomyl. It is a white crystalline solid that is soluble in most organic solvents and has a melting point of approximately 160-162°C. Benomyl-d4 is commonly used in agriculture to prevent and control a wide range of plant diseases caused by fungi, including powdery mildew, leaf spot, and rust. It works by disrupting the growth and reproduction of the fungi, ultimately leading to their death. Chemically, Benomyl-d4 is a benzimidazole derivative and contains two main functional groups: a benzene ring and an imidazole ring. The deuterium atoms (heavy isotopes of hydrogen) are located on the methyl group of the benzene ring, which allows for the compound to be easily distinguished from non-deuterated Benomyl in analytical studies. Benomyl-d4 has a relatively short half-life in soil and is considered to be moderately toxic to humans and the environment. Its use is regulated by government agencies to ensure safe handling and disposal. Overall, Benomyl-d4 is a useful tool for plant disease management and research, providing a valuable tool for understanding the mechanisms of fungal growth and development.
