To prepare 2-cyano-3-nitropyridine, there are various methods.
First, pyridine is used as the starting material. Pyridine is first nitrified to obtain 3-nitropyridine. Under appropriate reaction conditions, 3-nitropyridine undergoes nucleophilic substitution reaction with cyanide reagents, such as cuprous cyanide, etc. The nitro group is replaced by cyano, so 2-cyano-3-nitropyridine is obtained. In this process, the nitration step needs to be controlled by the reaction conditions. Temperature and reagent ratio have an impact on the yield and purity of the product. During nucleophilic substitution, factors such as the activity of the cyanide reagent and the reaction solvent also need to be carefully considered.
Second, we can start from 2-methyl-3-nitropyridine. 2-methyl-3-nitropyridine is oxidized to convert methyl to carboxyl, resulting in 2-carboxyl-3-nitropyridine. After the carboxyl group is reacted with ammonia to form an amide and then dehydrated, 2-cyano-3-nitropyridine can be obtained. It is crucial to choose the appropriate oxidizing agent for the oxidation process, and the appropriate reagents and conditions for the amidation and dehydration steps.
Third, it is prepared from the corresponding halogenated pyridine. If 2-halogen-3-nitropyridine (halogen can be chlorine, bromine, etc.) is selected, and the cyanide reagent is substituted with nucleophilic substitution in the presence of catalyst, and the halogen atom is replaced by cyanyl group, the target product can also be obtained. In this path, the activity of halogenated pyridine, the characteristics of cyanide reagents, and the type and dosage of catalysts all affect the process and effect of the reaction.
All these methods have advantages and disadvantages. In actual preparation, the optimal method should be selected according to various factors such as the availability of raw materials, cost, difficulty of reaction, and purity and yield of the product.

2-hydroxy- 3-methoxybenzaldehyde, this is an organic compound. Among its physical properties, its appearance is often colorless to light yellow liquid, and it persists stably at room temperature and pressure. Its boiling point is quite high, about 260 degrees Celsius, which makes it start to boil into a gaseous state at a specific temperature environment. The melting point is relatively low, about minus ten degrees Celsius, which means that it can still maintain a liquid state at relatively low temperatures.
Its density is slightly higher than that of water, about 1.12-1.13 g/cm3, so when mixed with water, it will sink to the bottom. In terms of solubility, it is difficult to dissolve in water, but it is easily soluble in organic solvents such as ethanol and ether. This characteristic is due to the fact that its molecular structure contains benzene ring, hydroxyl group and methoxy group. The benzene ring is a hydrophobic group. Although the hydroxyl group and methoxy group have a certain hydrophilicity, it is not enough to dissolve it in water. The organic solvent is compatible with the intermolecular force of the compound, so it is easy to dissolve.
It has a special odor, fragrance and certain irritation. This odor characteristic may have applications in the fields of fragrance preparation. In addition, the compound will gradually undergo oxidation and other reactions over time in light and air, resulting in a slightly darker color and subtle changes in physical properties. Pay attention to this when storing and using. Its physical properties determine the application direction and method in many fields such as chemicals, medicine, and fragrances.
