What are the physical properties of 2-chloro-3-iodine-4-methoxypyridine?
The physical properties of 2-% -3-chloro-4-aminoethoxybenzene are as follows:
This substance is often white to white crystalline powder. Its melting properties are specific, usually at a specific temperature. It is important to mention this substance. Due to different degrees of solubility, its melting properties may vary slightly.
In terms of solubility, it has a certain solubility in common solutions, such as ethanol, acetone, etc. Ethanol is commonly used as a solvent. The molecule contains both a heterogeneous group and a non-heterogeneous ethyl group. Due to its molecular properties, 2-% -3-chloro-4-aminoethoxy benzene can form a certain molecular force on ethanol molecules, so it can be dissolved in ethanol. In water, its solubility is small, and due to the solubility of water, the interaction of 2-% -3-chloro-4-aminoethoxy benzene molecules is limited.
The density of this substance is also one of its physical properties. The size of the density reflects the amount of its position. Under a specific degree of force, the density remains constant. This property is very important in multi-processing and operation, depending on the amount of material.
In addition, the outer crystal form is also worth noting. The different crystal forms do not affect the outer crystal shape, and may also affect the physical properties, such as quality and solubility. Under different crystal conditions, factors such as degree of solubility, solubility, and crystallization rate may cause 2-% 3-chloro-4-aminoethoxybenzene to form different crystal forms.
What are the synthesis methods of 2-chloro-3-iodine-4-methoxypyridine?
To prepare 2-cyanogen-3-chloro-4-methoxypyridine, there are three methods.
First, pyridine is used as the starting material, and the methoxy group is introduced before the pyridine ring. A suitable base agent, such as potassium carbonate, can be selected to react with a methoxy-containing reagent, such as dimethyl sulfate, in an organic solvent, such as N, N-dimethylformamide, and heated to co-react, so that the methoxy group replaces the corresponding hydrogen atom on the pyridine ring. Then, a chlorine-based reagent, such as phosphorus oxychloride, reacts under appropriate conditions to introduce a chlorine atom. Finally, after cyanidation, a cyanide reagent, such as cuprous cyanide, is used to introduce the cyanyl group in a specific solvent and temperature to obtain the target product.
Second, starting from the easily available pyridine derivatives, if there are already pyridine derivatives containing some of the desired substituents, they can be converted by functional group conversion. For example, there are first pyridine compounds containing methoxy groups and other convertible groups, and the convertible groups can be gradually converted into chlorine atoms and cyano groups by suitable reactions. For example, a reactive group can be replaced with chlorine atoms by a halogenation reaction, and then a cyanide group can be introduced through a nucleophilic substitution reaction. During this period, attention should be paid to the control of reaction conditions to prevent side reactions from occurring.
Third, the cyclization reaction strategy can be used. Select the appropriate chain compound, containing the functional group that can build the pyridine ring in the reaction and introduce the corresponding substituent. For example, the chain molecule containing methoxy, chlorine atoms and cyanyl potential reaction check points, under the appropriate catalyst, such as metal catalyst, and under specific reaction conditions, the molecular cyclization reaction occurs to construct the pyridine ring structure, and at the same time form 2-cyano-3-chloro-4-methoxy pyridine. This approach requires fine design of the structure of the starting chain compound and precise control of the reaction conditions to improve the yield and purity of the target product.
