Direct sale of chemical and pharmaceutical intermediates

Pesticide intermediates are products produced by the processing of agricultural raw materials, an intermediate medium that combines two or more substances together. In pesticides can be understood as synergists, is the production of pesticides intermediate materials. Common types: plant growth regulators: aminopyralid (DA-6), clopyralid (KT-30), sodium dinitrophenate, 6-BA, cytokinin, α-naphthalene acetic acid sodium, 5-nitro guaiacol sodium, indole butyric acid and so on. Pesticide intermediates in pesticides can be understood as synergists, is the production of pesticides intermediate materials. That is, the agricultural raw materials processed and produced products, is a kind of intermediate medium that combines two or more substances together. In our country pesticide intermediates can generally be divided into two categories, pesticide intermediates containing heterocyclic and pesticide intermediates containing fluorine.

Content

Fluorine-containing pesticide intermediates In the search for ways to improve biological activity, fluorine is often used in place of hydrogen or chlorine. This substitution can greatly improve the efficacy of pesticides, and the introduction of fluorine atoms into the structure of pyrethroids increases the efficacy against pests and has an acaricidal effect, so fluorinated pyrethroids have been of interest. However, it is necessary to select the fluorine substituent position of the molecule to prepare the most active compounds. Fluorine atom insertion plays a key role in biological activity, but fluorine substitution of hydrogen often reduces the activity, however, the most active compounds often contain fluorine atoms in some positions of the molecular structure, and to prepare fluorine-containing compounds with high activity, fluorine-containing intermediates are necessary, so research and development of fluorine-containing intermediates become very necessary.
