1H-pyrrolo[2,3-b]pyridine-3-carbaldehyde

The chemical structure of 1H-pyrrole [2,3-b] pyridine-3-formaldehyde is a heterocyclic compound formed by the fusing of pyrrole and pyridine. Among them, the pyrrole ring fuses with the pyridine ring in a specific way to form a unique double ring structure. In this structure, 1H indicates that the first position of the pyrrole ring is occupied by a hydrogen atom; "pyrrole [2,3-b] pyridine" clearly defines the connection check point and fusing method of the pyrrole ring and the pyridine ring; while - 3-formaldehyde means that there is an aldehyde group (-CHO) attached to the third position of the fused heterocyclic ring. This aldehyde group endows the compound with specific chemical activities and reaction characteristics. In the field of organic synthesis, it can often be used as a key reaction check point, participating in many important organic reactions, and then deriving more complex and diverse organic compounds. This structure is unique and has specific chemical properties, showing broad application prospects and research value in many fields such as medicinal chemistry and materials science.

The common synthesis methods of 1H-pyrrolido [2,3-b] pyridine-3-formaldehyde are a subject of great concern in the field of organic synthesis. There are several common methods for its synthesis.
First, it can be obtained by the conversion of nitrogen-containing heterocyclic compounds through specific reactions. If a suitable pyridine derivative is used as the starting material, the pyrrole ring structure is introduced, and then the formylation reaction is carried out at a specific position. This process requires delicate control of the reaction conditions, and the choice of temperature and catalyst is the key. If the temperature is too high, side reactions may occur, and the product is impure; if the temperature is too low, the reaction rate will be slow and take a long time. The activity and selectivity of the catalyst also have a significant impact. If the activity is too high or unnecessary reactions are triggered, and if the selectivity is not good, it is difficult to obtain the target product.
Second, the reaction path catalyzed by transition metals can be used. Transition metals such as palladium and copper often play a key role in this synthesis. Taking palladium catalysis as an example, through the coupling reaction catalyzed by palladium, different reaction fragments are cleverly connected to build the skeleton of the target molecule. Although this path is efficient, transition metals are expensive, and the removal of metal residues after the reaction is also a challenge, and the post-treatment process needs to be carefully designed to ensure that the purity of the product meets the requirements.
Third, strategies based on cyclization reactions are also commonly used. Select a linear compound with suitable functional groups, initiate intramolecular cyclization under appropriate conditions, form the core structure of pyrrolidine, and then introduce aldehyde functional groups. This method requires careful design of the structure of the starting material to ensure the smooth progress of the cyclization reaction. At the same time, the aldehyde group introduction step also needs to pay attention to the selectivity and yield of the reaction.
All these synthetic methods have their own advantages and disadvantages. In practical applications, the appropriate synthetic route should be carefully selected according to specific requirements, such as product purity, cost considerations, reaction scale and other factors, in order to achieve the best synthetic effect.

1H-pyrrolido [2,3-b] pyridine-3-formaldehyde is an organic compound. Its physical properties are particularly important, which is related to the performance and use of this substance in different scenarios.
Looking at its appearance, under room temperature and pressure, it is mostly white to light yellow solid powder. This form is easy to store and transport, and when the powdered substance participates in the chemical reaction, due to its large surface area, it is easier to contact with other reactants and promote the reaction.
When it comes to the melting point, it is about 142-146 ° C. As an inherent characteristic of the substance, the melting point is of great significance for the identification and purification of this compound. Knowing the melting point, its purity can be identified by melting point measurement experiments. If the purity of the substance is high, the melting point range is narrow and close to the theoretical value; if it contains impurities, the melting point decreases and the melting range becomes wider.
In addition to solubility, this compound has good solubility in common organic solvents such as dichloromethane, N, N-dimethylformamide (DMF). This property makes it widely used in the field of organic synthesis. Due to the fact that many organic reactions are carried out in solution, good solubility ensures that it can be uniformly dispersed in the reaction system, improving the reaction efficiency. However, its solubility in water is not good, which is mainly due to the relatively small number of hydrophilic groups in the molecular structure of the compound, and the large proportion of hydrophobic aromatic ring structure, which makes the interaction force between it and water molecules weak.
In addition, the density of the substance is about 1.34 g/cm ³. Density, as a physical constant, plays a key role in determining the amount of substance and calculating the volume of the reaction system in chemical production and other fields. The physical properties of 1H-pyrrolido [2,3-b] pyridine-3-formaldehyde, such as its appearance, melting point, solubility, density, etc., have a profound impact on its applications in many fields such as organic synthesis and drug development. It is an important basis for in-depth research and rational application of this compound.

1H-pyrrolido [2,3-b] pyridine-3-formaldehyde is difficult to say in a word in terms of the current market price. Its price fluctuates due to a variety of reasons.
First, it is related to the difficulty of preparation. If the preparation method is complicated, rare raw materials are required, after many fine steps, and the yield is not high, the price will be high. On the contrary, if the preparation method is simple, the raw materials are easy to purchase and inexpensive, and the yield is acceptable, the price is close to the people.
Second, it depends on the amount of market demand. If there is a strong demand for this product in the fields of pharmaceutical research and development, materials science, etc., but the supply is relatively short, the so-called "rare is expensive", its price will rise. If there is little demand and excess supply, the price will decline.
Third, the situation of market competition also has an impact. If many merchants in the market sell this product, the competition is fierce, and the price may be reduced for customers. If the merchants are rare and almost monopolized, the price may remain high.
Furthermore, the macroeconomic situation and changes in policies and regulations will also affect its price. Economic prosperity, the purchasing power of money is strong, and the price may be slightly higher; economic malaise, the purchasing power decreases, and the price may also be suppressed. If the policy restricts or supports production and trade, it will also cause prices to fluctuate.
Therefore, if you want to know the exact market price of 1H-pyrrole [2,3-b] pyridine-3-formaldehyde, you must carefully observe the current preparation process, market supply and demand, competition landscape and economic policies, etc., in order to obtain a more accurate number, which cannot be speculated out of thin air.
