4-Hydroxy-1H-pyrimidin-6-one is usually used as fine chemical raw materials or organic synthesis intermediates, which is widely used in the preparation of pharmaceuticals, pesticides and fungicides. For example, in the pharmaceutical industry, it can be used to produce the intermediates of sulfonamides such as sulfotoxin, vitamin B4, antitumor drugs and auxiliary drugs; In addition, it can also be used as an intermediate for the synthesis of Methoxyacrylate fungicides.

2,6-Dichlorobenzonitrile itself is a herbicide variety diquaturon, and it is also an important intermediate in the synthesis process of benzoylurea insecticides. It is used to synthesize the next intermediate 2,6-difluorobenzonitrile, and finally get flufenuron, diflubenzuron, flupicuron, delphamide and other pesticides.

Difenoconazole, a triazole fungicide, is a sterol demethylation inhibitor with high efficiency, broad spectrum, low toxicity and low dosage. It is an excellent variety of triazole fungicides with strong internal absorption. It can destroy the structure and function of pathogen cell membrane by inhibiting the biosynthesis of ergosterol in pathogen cells. It is used in fruit trees, vegetables, wheat, potatoes, beans, etc Cucurbits and other crops have good protection and treatment effects on vegetables, fruits and other fungal diseases, and have the characteristics of "three no" (no pollution of the environment, no pollution of agricultural products, no killing of natural enemies). They are ideal fungicides for controlling citrus scab, leaf spot and other crop resistant diseases in China and even in the world.

Indole exists in feces, coal tar, jasmine oil and Neroli oil. It is colorless, lobular or plate-shaped crystal. It has strong fecal odor. The pure product has fresh flower odor after dilution. It is soluble in hot water, benzene and petroleum. It is easily soluble in ethanol, ether and methanol. It can volatilize with water vapor. It turns red when placed in air or visible light, and resinifies. It is weakly acidic and forms salt with alkali metals, It is resinified or polymerized with acid. The highly diluted solution has jasmine fragrance and can be used as perfume. Indole is an important organic raw material and fine chemical product. Its homologues and derivatives widely exist in nature, mainly in natural flower oil, such as jasmine, sweet orange, white lemon, pomelo peel, orange, bitter orange, Narcissus, vanilla, etc. It can be widely used in jasmine, Syringa, orange blossom, gardenia, honeysuckle, lotus, Narcissus, Yilan, orchid, and prune. It is often used in combination with methyl indole to make artificial civet flavors. It can be used in chocolate, raspberry, strawberry, bitter orange, coffee, nuts, cheese, grape and fruit flavor compound.

Cyazofamid is a kind of sulfaimidazole fungicide. It has high biological activity against oomycetes such as Phytophthora, frost mold, pseudofrost mold, Pythium and Brassica Rhizopus. Suitable crops are potatoes, grapes and vegetables (cucumber, cabbage, tomato, onion and lettuce). The control objects are downy mildew and epidemic diseases, such as cucumber downy mildew, grape downy mildew, tomato late blight, potato late blight, etc.
