What is the main use of n- (benzo [b] thiophene sulfone-2-methoxycarbonoxy) succinimide

(Nitrate [B] sulfatrazine-2-aminophenoxyphenoxypropionic acid) The main use of water emulsion is related to the control of weeds in farmland. This agent can remove many weeds in the field. It can effectively target annual and perennial weeds to protect the growth environment of crops.

In corn fields, many grasses weeds, such as the genus Matang and barnyardgrass, as well as broad-leaved weeds, such as quinoa and amaranth, can be inhibited by this agent. After applying this agent, the growth of weeds is blocked and gradually withers. Its mechanism of action interferes with the physiological and biochemical processes of weeds, making them unable to take up nutrients normally, perform photosynthesis, and eventually die. < Br >
It is also available in other dryland crop fields. It can help farmers control weed breeding, reduce the labor of manual weeding, and improve crop yield and quality. It uses water as a substrate and forms a water milk state. Compared with traditional dosage forms, it is more environmentally friendly, can reduce the adverse impact on the environment, and is easier to operate when applying medicine. Therefore, in the field of weed control in modern agriculture, this water emulsion occupies an important place and is a right-hand assistant for agricultural activities.

What are the synthesis methods of n- (benzo [b] thiophene sulfone-2-methoxycarbonoxy) succinimide

There are several ways to prepare nitro- (hydrazine [b] indazole-2 -aminohydroxyhydroxylamine) guanidine nitrate.

First, hydrazine [b] indazole-2 -aminohydroxyhydroxylamine is used as a group, and guanidine is added through a specific reaction, and then reacts with nitric acid to form a salt. This requires precise control of the reaction temperature, time and material ratio. At the beginning of the reaction, the reaction system was adjusted at a suitable temperature, and guanidine reagents were slowly added to catalyze the reaction, so that the guanidine group was effectively combined with hydrazine [b] indazole-2 -aminohydroxyhydroxylamine. Then, nitric acid is added dropwise, and the reaction process is observed. To form a stable salt, crystallize, filter, wash, and dry to obtain the product.

Second, the precursor of guanidine nitrate can be prepared first, and then reacted with hydrazine [b] indazole-2-aminohydroxylamine. First take guanidine compounds, treat them with acid to form guanidine salts, and then react with hydrazine [b] indazole-2-aminohydroxylamine in an appropriate solvent. It is very important to choose a good solvent, which needs to have good solubility to the two and no side reactions. During the reaction, stir to promote contact, and control the temperature to stabilize the reaction rate. After the reaction is completed, the pure product is obtained by separation and purification. < Br >
Third, the one-pot method is adopted. Hydrazine [b] indazole-2-aminohydroxyhydroxylamine, guanidine reagents and nitric acid are put into the reactor in a certain order and amount. Although this is simple, the control of the reaction conditions is more stringent. It is necessary to precisely adjust the temperature and stir quickly to make the reaction proceed in sequence and efficiently to avoid the clustering of side reactions. After the reaction, the target product is obtained after post-treatment, such as extraction, recrystallization, etc.

All these methods have advantages and disadvantages. It is necessary to choose carefully according to the availability of raw materials, the conditions of equipment, the purity and yield of the product, etc., before the optimal method can be obtained for the preparation of nitrogen- (hydrazine [b] indazole-2-aminohydroxyhydroxylamine) guanidine nitrate.

What are the physicochemical properties of n- (benzo [b] thiophene sulfone-2-methoxycarbonoxy) succinimide

(Nitrogen- (pyridine [b] indole-2 -aminophenyloxy) phosphoryl dichloroethyl ester) has the following physicochemical properties:

The appearance of this compound may be solid or liquid, depending on its chemical structure and environmental conditions. In terms of solubility, it may have some solubility in non-polar or weakly polar solvents such as dichloromethane and chloroform. Because the compound contains organic groups, it matches the intermolecular forces of such solvents and can be dissolved through interactions such as van der Waals forces. However, in water, due to the hydrophobicity of its structure, the solubility is highly likely to be low.

Thermal stability, it will be affected by the strength and structure of the chemical bonds within the molecule. If there are stable conjugated systems or strong chemical bonds in the molecule, such as aromatic ring structure and phosphorus-oxygen chemical bonds, it can enhance the stability of the molecule, and decomposition or structural changes may occur at higher temperatures. However, if there are some fragile weak bonds in the molecule, such as some ester bonds or unstable substituents, the thermal stability will be reduced.

From the perspective of chemical activity, the phosphoryl groups in the molecule have certain reactivity and can participate in nucleophilic substitution reactions, such as reacting with compounds containing hydroxyl groups and amino groups to form new phosphorus esters or phosphoramides. At the same time, the aromatic ring of pyridine [b] indole and amino phenyloxy can participate in the electrophilic substitution reaction, and other substituents are introduced into the aromatic ring under suitable reaction conditions and reagents, so as to realize the structural modification and functional change of the compound.

What is the price range of n- (benzo [b] thiophene sulfone-2-methoxycarbonoxy) succinimide in the market?

It is difficult to determine the range of the price of this nitrate (boron [b] sand alkali alum-2-aminohydroxyoxy) fire nitrate and alum in the market. Covered with the change of prices, it is always dependent on various factors, such as the amount of production, the urgency of the request, and the difference in time.

However, roughly speaking, this nitrate (boron [b] sand alkali alum-2-aminohydroxyoxy) fire nitrate and alum, if the quality is normal and the market is average, the price per two may be between ten and thirty dollars. If its quality is high, and there are many people in the market, the price may increase to fifty dollars, or even higher. On the contrary, if the product is abundant and the buyer is scarce, the price may be reduced to five coins.

Also, the city is located in different places, and the price varies. Prosperous cities, where merchants gather together, seek more and the price is always high; remote cities, where more is produced and less is sought, the price is low. And with time and year, the four seasons are different, and the price also changes. Therefore, if you want to know the exact price, you can only get it if you are in the city and observe it, and inquire about all merchants.
