5H-Pyrrolo[3,4-b]pyridine, 2-chloro-6,7-dihydro-

5H-pyrrolido [3,4-b] pyridine, 2-chloro-6,7-dihydro, its physical properties are as follows:
This substance is either solid at room temperature, looking at its appearance, or in a white to light yellow powder form, due to the characteristics of atomic arrangement and electron cloud distribution in the structure of such compounds. Its melting point is an important physical parameter, which is within a certain range, but the exact value will vary depending on the purity of the sample and the measurement conditions.
In terms of solubility, it may have a certain solubility in organic solvents, such as common ethanol, dichloromethane, etc. Because the molecular structure of the compound contains polar and non-polar parts, it can form van der Waals forces, hydrogen bonds and other interactions with organic solvent molecules. In water, the solubility is relatively small due to the hydrophobicity of chlorine atoms and cyclic structures. The value of
density is also one of its physical properties, depending on its molecular weight and the degree of molecular packing compactness, it is roughly within a certain range.
In addition, due to the cyclic structure containing conjugated double bonds, the compound may exhibit absorption and emission phenomena under light irradiation of specific wavelengths, which has unique characteristics in the field of spectroscopy. In its crystal structure, atoms are connected by specific bond lengths and bond angles, forming a stable three-dimensional spatial structure, which also has a key impact on the manifestation of its physical properties.

This is 2-chloro-6,7-dihydro-5H-pyrrolido [3,4-b] pyridine, and its chemical properties are unique.
First of all, its physical characteristics are under room temperature, or in the state of a solid state. However, its specific melting point and boiling point are difficult to determine because there is no detailed data. Looking at its molecular structure, which contains chlorine atoms and pyrrolido-pyridine skeletons, this structure gives it specific chemical activity.
When it comes to chemical activity, chlorine atoms are active groups that can initiate many reactions. First, the nucleophilic substitution reaction, because the chlorine atom has good departure properties, if it encounters nucleophilic reagents, such as alcohols and amines, the chlorine atom is easily replaced. Taking alcohols as an example, under suitable alkali catalysis conditions, the oxygen atom of the alcohol acts as the nucleophilic center, which can attack the carbon atom connected to chlorine, and the chlorine atom leaves to generate the corresponding ether derivatives. This reaction is often a key step in the construction of new compounds in organic synthesis.
Furthermore, its unsaturated pyrrolido-pyridine skeleton has a certain conjugate system, so it can participate in the addition reaction. For example, with electrophilic reagents, such as hydrogen halides, halogens, etc., additions can occur. In the case of hydrogen halide, hydrogen atoms can be added to the ortho-position of the nitrogen atom in the pyridine ring, and halogen atoms can be added to its para-position to form a new saturated bond, thereby changing the degree of unsaturation of the molecule and the distribution of the electron cloud.
In addition, because the nitrogen atom on the pyridine ring has a lone pair of electrons, it has a certain alkalinity and can react with acids to form corresponding salts. The formation of this salt may change the physical properties such as solubility of the compound, which may be of great significance in practical applications such as drug preparation, separation and purification.

There are currently methods for the synthesis of 2-chloro-6,7-dihydro-5H-pyrrolido [3,4-b] pyridine, which are described in detail below.
The starting material is often a pyridine derivative with a suitable substituent, which is the key substrate. At the beginning of the reaction, an appropriate reaction environment needs to be selected, such as selecting a suitable organic solvent to create a suitable pH, which is the basis for the smooth initiation of the reaction.
The pyridine derivative may first meet the chlorine-containing reagent, which may be sulfoxide chloride, phosphorus oxychloride and the like. When the two meet, through the mechanism of nucleophilic substitution, the chlorine atom then enters the specific position of the pyridine ring to form the chlorinated pyridine intermediate. In this step, the control of temperature and time is very important. If the temperature is too high, it will cause a cluster of side reactions, and if it is too low, the reaction will be delayed, which needs to be carefully weighed.
Wait for the chlorinated intermediate to be obtained, and continue the great business of constructing pyrrole rings. Or introduce reagents with active hydrogen and unsaturated bonds, and use basic catalysts to help, through cyclization, pyrrole rings will gradually form. In this process, the amount of basic catalysts and the properties of the reaction solvent have a profound impact on the reaction process and product configuration.
There may be other ways. Starting from a nitrogen-containing heterocyclic precursor, it is first transformed into a specific functional group to obtain a compound with a potential reaction check point. Then reacting with suitable halogenated hydrocarbons, through a series of nucleophilic substitution and cyclization rearrangement steps, the purpose of synthesizing 2-chloro-6,7-dihydro-5H-pyrrolido [3,4-b] pyridine can also be achieved.
In the process of synthesis, the reaction products in each step need to be separated and purified, such as column chromatography, recrystallization, etc., to remove impurities and obtain pure products. Optimization of the reaction conditions at each step depends on repeated experiments, observing the change of product yield and purity, adjusting factors such as temperature, reagent ratio, and reaction time, in order to find a good method for efficient synthesis of this compound.

The price of 2-chloro-6,7-dihydro-5H-pyrrolido [3,4-b] pyridine is on the market in Wuweiwen. This is a fine chemical, which is not commonly seen. Its synthesis is quite complex, involving multi-step reactions, demanding reaction conditions, and the raw materials used may be rare.
In the field of chemical trade, the price often depends on the state of supply and demand, the quality of the product, and the difficulty of preparation. If the demand for this product is strong and the supply is scarce, the price will not be cheap. On the contrary, if the supply exceeds the demand, the price may drop.
Also, quality is also the key to pricing. The price of high purity is higher than that of low purity due to high preparation cost. And the different preparation processes will also lead to differences in cost and quality, which will affect the price.
Furthermore, regional differences also have an impact. In the place where the chemical industry gathers, due to the easy availability of raw materials and convenient logistics, the cost may be reduced, and the price may be different.
However, it is difficult for me to determine the market price. If you want to know, you can consult chemical raw material suppliers, chemical reagent distributors, or check chemical product trading platforms to get the exact price.
