4-bromo-1-methyl-2-nitro-imidazole

4-Bromo-1-methyl-2-nitroimidazole is also an organic compound. Its chemical properties are unique and have a variety of characteristics.
In this compound, bromine atoms, methyl groups, nitro groups interact with imidazole rings, resulting in specific chemical activities. Bromine atoms are active and can participate in nucleophilic substitution reactions. Because of their high electronegativity, they can make the connected carbon atoms partially positively charged, vulnerable to attack by nucleophilic reagents, and new compounds are generated by being replaced with bromine.
Methyl has an electron-pushing effect, which can affect the electron cloud density of imidazole rings, which in turn has an effect on the stability and reactivity of compounds. It can slightly increase the electron cloud density of the imidazole ring adjacent and para-position, and guide the selectivity of the reaction check point in some reactions. The nitro group at the
2-position is a strong electron-absorbing group, which significantly reduces the electron cloud density of the imidazole ring, makes the imidazole ring more stable, but also makes it difficult to occur electrophilic substitution reactions on the ring. At the same time, the nitro group can be reduced under suitable conditions and converted into other functional groups such as amino groups, thereby expanding the derivation pathway of compounds. The synergy effect of the above functional groups of 4-bromo-1-methyl-2-nitroimidazoline is widely used in the field of organic synthesis, and can be used as a key intermediate to create various organic molecules with biological activity or special functions.

To prepare 4-bromo-1-methyl-2-nitro-imidazole, follow the following method.
First take 1-methylimidazole as the starting material, which is the key substrate. In an appropriate reaction vessel, add an appropriate amount of 1-methylimidazole, and then introduce brominating reagents. Commonly used brominating reagents such as bromine (Br ²) or N-bromosuccinimide (NBS). If bromine is used, it should be slowly added dropwise in a well-ventilated environment and at low temperature because of its strong corrosiveness and volatility. When N-bromosuccinimide is used, the reaction is relatively mild. The purpose of this step is to bromide the specific position of 1-methylimidazole. In the presence of suitable catalysts and solvents, such as carbon tetrachloride, under the action of light or initiator, the bromine atom selectively replaces the hydrogen atom at the specific position on the imidazole ring to generate 4-bromo-1-methylimidazole.
After 4-bromo-1-methylimidazole is obtained, the nitrification reaction is continued. Place 4-bromo-1-methylimidazole in another reaction vessel and add a nitrifying agent. The commonly used nitrifying reagent is mixed acid, that is, concentrated nitric acid and concentrated sulfuric acid are mixed in a certain proportion. This mixed acid has strong oxidizing and nitrifying ability. Under low temperature and strict temperature control, the mixed acid is slowly added dropwise to the system containing 4-bromo-1-methylimidazole. Concentrated sulfuric acid is not only a dehydrating agent, but also helps to generate nitroyl positive ions (NO ²), which is an active species of nitrification reaction. During the reaction process, the temperature is closely monitored to prevent side reactions from occurring. After this nitrification step, 4-bromo-1-methyl-2-nitro-imidazole can be obtained. < Br >
However, after the reaction is completed, the product often contains impurities, which need to be separated and purified. Column chromatography can be used to select an appropriate stationary phase and eluent, and separation can be achieved according to the difference in the distribution coefficients between the product and the impurities in the stationary phase and the eluent. Recrystallization can also be used to select an appropriate solvent to dissolve the product in a hot solvent, crystallize and precipitate after cooling, and the impurities remain in the mother liquor to obtain pure 4-bromo-1-methyl-2-nitro-imidazole.

4-Bromo-1-methyl-2-nitroimidazole is in the market, what is the price? This is a fine chemical, used in medicine, pesticide synthesis and other fields. However, its market price varies depending on purity, supply and demand, and manufacturers.
Looking at past transactions, if the purity is ordinary, it is about ten yuan per gram. However, if the purity is high, the price may increase several times. If the purchase volume is large, the manufacturer may make a profit to reduce the unit price.
When the market demand exceeds the supply, the price will rise; if the supply exceeds the demand, the price will drop. And different manufacturers have different pricing due to cost differences. Large manufacturers produce standard, the cost may be high, and the price is also high; small manufacturers may have lower prices due to low costs.
To know the exact price, you must consult chemical raw material suppliers, chemical reagent companies, or check on the chemical trading platform to get the current market.
