Matrine
Matrine is an alkaloid extracted from the roots, stems and fruits of Sophora flavescens, a legume plant, by ethanol and other organic solvents. The main components of Sophora flavescens are matrine, Oxymatrine, sophocarpine, Oxysophocarpine, sophoridine and other alkaloids. The content of matrine and Oxymatrine is the highest. With different crystallization conditions, matrine has four crystal types: α - type: acicular, melting point 76 ℃; β - type: short prismatic, melting point 87 ℃; γ - type: oily liquid, static transformation to α - type; δ - type: leaflike or prismatic, melting point 84 ℃. These crystal forms can transform into the same salts. Relative density is 1.0888 (85 / 4 ℃), refractive index is 1.52865 (85 ℃) [α] d20-39.11 ℃ water. Soluble in cold water, ethanol, ether, chloroform and benzene, insoluble in petroleum ether, less soluble in hot water than in cold water. Oxymatrine was produced by hydrogen peroxide oxidation. Matrine and Oxymatrine are easy to dissolve in water. However, the oxygen atoms in Oxymatrine share a pair of electrons with N atoms through a semi polar coordination bond, which is similar to alkaloid salts to a certain extent and has a large polarity. Therefore, the solubility in water is higher than that of matrine, and the solubility in organic solvent is lower than that of matrine.

It is especially suitable for nylon 6 and nylon 6, 6, which are two kinds of pure nylon. It has good flame-retardant effect, small processing smoke, and can easily achieve ul94v-o flame-retardant level. It has very low application cost, superior electrical properties, mechanical properties and coloring properties. At the same time, when it is used as a mixed additive to manufacture flame-retardant masterbatch, due to its self Excellent balance between good thermal stability and high efficiency flame retardant, so it has the advantage of easy processing.
Mesotrione
Mesotrione is a herbicide that works by inhibiting 4-hydroxyphenylpyruvate dioxygenase (HPPD), a crucial enzyme for the biosynthesis of carotenoid in plants. Mesotrione is also a synthetic analog of l epospermone.
Metaflumizone
Cyfluzonazone is a new mechanism of action of insecticides, through the attachment to the receptor of sodium ion channel, blocking the passage of sodium ion, and no cross resistance with pyrethroids or other kinds of compounds. The drug is mainly through insect feeding into its body to produce stomach poison to kill pests, with little contact killing effect and no inhaling effect. The drug has a good control effect on target pests and larva of all ages. After the insect is fed, the drug enters the insect body, blocks the sodium ion channel on the axon membrane of the insect neuron through a unique mechanism of action, so that the sodium ion cannot pass through the axon membrane, and then suppresses the nerve impulse to make the insect body relax and paralyze excessively. After a few hours, the insect stops feeding and dies within 1-3 days.
