2-Hydroxy-4-methyl-3-nitropyridine

2-Hydroxy-4-methyl-3-nitropyridine, this material property is special, and it is related to the delicacy of chemistry. Its color state is often solid or powder, fine and uniform. Looking at its color, it may be slightly yellow, but there is a faint light, just like the first light of the morning sun.
As for the degree of melting and boiling, the melting point is about a specific temperature, because of the intermolecular force. When heated, the lattice gradually relaxes, until the melting point and the state of matter begins to change, from solid into the liquid, as if it were frozen in the spring sun. The boiling point requires a higher temperature, and then the molecules break free from the liquid phase and escape into the gas phase, like birds flying in the sky.
Solubility is also an important property. In water, its solubility is limited, but in organic solvents, such as alcohols and ethers, or soluble. This is due to the principle of similar miscibility, molecular polarities match, so they are miscible, like a duck in water, and they blend seamlessly.
In terms of chemical activity, its pyridine ring is aromatic and has a special distribution of electron clouds. Hydroxyl groups can be acidic and can react with bases, like acid and base, to form corresponding salts. Methyl adds its fat solubility, which affects the intermolecular interaction. Nitro is a strong electron-absorbing group, which decreases the electron cloud density of the pyridine ring, changes the reactivity on the ring, makes electrophilic substitution more difficult, and nucleophilic substitution may occur more easily, just like on the stage of chemical reactions, the role changes accordingly, and a different kind of chemical drama is deduced. And nitro also makes this substance potentially oxidizing. Under suitable conditions, it can participate in oxidation and reduction reactions, adding brilliance to chemical changes.

The synthesis method of 2-hydroxy-4-methyl-3-nitropyridine is recorded in the ancient books, and there are many ways. First, with 4-methyl pyridine as the starting material, the nitro group is introduced at the 3rd position of the pyridine ring through the nitrification method, and then oxidized, and the hydroxyl group is introduced at the 2nd position. During this process, the nitrification step requires careful selection of nitrifying reagents. The mixed acid of nitric acid and sulfuric acid is commonly used, but the reaction conditions are severe, and the temperature and ratio need to be precisely controlled, otherwise side reactions will occur. When oxidizing, it is also crucial to choose a suitable oxidant, such as potassium permanganate, etc., but its selectivity may be insufficient.
Second, pyridine derivatives containing corresponding substituents are used as raw materials and obtained by functional group conversion. For example, those with suitable substituents and easy conversion to hydroxyl and nitro groups are selected, and the structure of the target molecule is gradually constructed through a series of reactions such as halogenation, cyano substitution, and hydrolysis. Although this approach is complicated, the selectivity of each step is easy to control, and the purity of the product may be improved. Halogenation requires the selection of a suitable active halogenating agent, and conditions such as lighting and catalysts are also related to the reaction process. Cyanide substitution and hydrolysis steps also have specific requirements on the reaction medium, temperature and other conditions.
Third, by means of heterocyclic synthesis, small molecules containing nitrogen and oxygen are used as raw materials to construct pyridine rings through cyclization reaction, and the required substituents are introduced synchronously. This path requires delicate design of reaction substrates and reaction conditions, so that the cyclization reaction can occur in a directional manner, in order to achieve the purpose of synthesizing the target product. For example, compounds containing nitrogen and carbonyl groups are selected, and 2-hydroxy-4-methyl-3-nitropyridine is obtained through cyclization and substitution in a suitable catalyst and solvent environment. Among them, the screening of catalysts and the optimization of the reaction system are the keys to success.
