5-nitro-1H-Pyrrolo[2,3-B]pyridine

5-Nitro-1H-Pyrrolo [2,3-B] pyridine is an organic compound with specific chemical properties. Its appearance is often solid, and its color may vary from light yellow to yellow, due to the presence of chromophore groups in the molecular structure.
From the perspective of chemical activity, nitro is a strong electron-absorbing group, which causes the compound to have certain reactivity. In nucleophilic substitution reactions, nitro can reduce the electron cloud density on the pyridine ring, making the carbon atoms on the ring more vulnerable to attack by nucleophiles. For example, if nucleophiles such as alkoxides and amines meet it, substitution reactions may occur at specific positions in the pyridine ring.
Its solubility is also an important property. Usually, this compound has a certain solubility in organic solvents such as dichloromethane and N, N-dimethylformamide, but its solubility in water is not good. This characteristic is due to its molecular structure, in which hydrophobic aromatic rings and pyridine rings account for a large proportion, and there are relatively few polar groups that can form hydrogen bonds with water.
In terms of thermal stability, under general conditions, the compound is relatively stable. However, when heated to a specific temperature, the nitro group may undergo reactions such as decomposition. Due to the limited thermal stability of the nitro group, gases such as nitrogen oxides may be released at high temperatures, causing structural changes in the compound. The chemical properties of 5-nitro-1H-Pyrrolo [2,3-B] pyridine are determined by its unique molecular structure. These properties are of great significance in organic synthesis, medicinal chemistry and other fields, and affect its performance in various chemical reactions and practical applications.

5-Nitro-1H-Pyrrolo [2,3-B] pyridine is an important organic compound, and its synthesis methods are diverse, and each has its own advantages. Several common synthesis methods are described in detail below.
First, the compound containing pyridine ring and pyrrole ring is used as the starting material, and nitro is introduced through nitrification reaction. In this process, the nitrification reagent and reaction conditions must be precisely selected. Common nitrifying reagents such as concentrated nitric acid and concentrated sulfuric acid mixed acid, the reaction temperature, time and the proportion of reactants have a great impact on the yield and purity of the product. If the temperature is too high, or side reactions such as excessive nitrification occur, which will damage the quality of the product; if the temperature is too low, the reaction rate will be slow and time-consuming.
Second, it is achieved by the strategy of constructing pyridine rings and pyrrole rings. Pyridine derivatives containing specific substituents can be prepared first, and then reacted with reagents containing pyrrole structures under suitable reaction conditions to construct pyrrolido-pyridine skeletons, and then nitro groups are introduced through nitration steps. The key to this approach lies in the optimization of the conditions for the construction of pyridine rings and pyrrole rings, such as the selection of appropriate catalysts, solvents and reaction temperatures. Different catalysts have significant effects on reaction activity and selectivity, and suitable solvents can promote the dissolution of the reactants and the reaction.
Third, the method of transition metal catalysis is adopted. Transition metal catalysts can efficiently catalyze the formation of various carbon-carbon and carbon-heteroatomic bonds. In the synthesis of 5-nitro-1H-Pyrrolo [2,3-B] pyridine, transition metals can be used to catalyze the coupling reaction between pyridine derivatives and pyrrole-containing substrates to construct the target molecular skeleton, and then nitro groups can be introduced through nitrification. The advantages of this method are that the reaction selectivity is high and the conditions are mild, but the transition metal catalyst is expensive and the post-reaction treatment may be complicated. It needs to be properly handled to recover the catalyst and ensure the purity of the product. < Br >

5-Nitro-1H-Pyrrolo [2,3-B] pyridine is an organic compound. However, it is difficult to determine its price range in the market. The change in price is influenced by many factors.
First, the difficulty of preparation is the key. If the synthesis of this compound is complicated, requires many steps, uses expensive reagents, or requires strict reaction conditions, the cost will be high, and the price will follow. On the contrary, if the preparation is easier, the raw materials are common and cheap, and the price should be low.
Second, the situation of market supply and demand also has a great impact. If there is a strong demand for this product in the fields of medicine, chemical industry, etc., but the supply is limited, the price will rise. If the demand is low and the supply is sufficient, the merchant will sell its goods or reduce its price.
Third, the production scale is also related. In large-scale production, due to the scale effect, the unit cost may be reduced, and the price may also be reduced. Small-scale production, the unit cost is high, and the price is also high.
Fourth, the purity of the product is also a factor affecting the price. High-purity 5-nitro-1H-Pyrrolo [2,3-B] pyridine is in high demand in special experiments and high-end applications, and its preparation difficulty is also high, so the price must be higher than that of low purity.
Overall, due to the complexity and variability of the above factors, in order to determine its market price range, it is necessary to consult chemical product suppliers, market survey agencies, or refer to relevant industry reports in real time to obtain more accurate price information.
