3-(Aminomethyl)pyridine

3- (aminomethyl) pyridine has a wide range of functions. In the field of organic synthesis, it is often used as a key intermediate. This substance can be derived from a variety of compounds with specific functions through various chemical reactions. For example, in pharmaceutical synthesis, it helps to create various drug molecules, or contributes to the construction of active parts of drugs, or is used to improve the physical and chemical properties and biological activities of drugs, such as improving the solubility and stability of drugs, and enhancing their affinity with targets.
In the field of materials science, 3- (aminomethyl) pyridine also has its uses. It can participate in the preparation process of polymer materials. By polymerizing with other monomers, it can impart novel properties to the material, such as improving the mechanical properties and thermal stability of the material, or imparting specific functions to the material, such as the adsorption and responsiveness of certain substances. In addition, it can also play a unique role in the preparation of functional polymer films and adsorption materials.
In addition, in the field of catalysis, it can also play a unique role. Or it can act as a ligand to form complexes with metal ions. As an efficient catalyst, it can catalyze various organic reactions and improve the rate and selectivity of the reaction. It is of great significance in the production practice of organic synthesis chemistry industry.
Furthermore, in the dye, pesticide and other industries, 3- (aminomethyl) pyridine is also used, or as a raw material to participate in the synthesis of dye molecules, giving dyes specific colors and properties; or in the synthesis of pesticides, it contributes to the creation of high-efficiency, low-toxicity and environmentally friendly pesticides.

To prepare 3- (aminomethyl) pyridine, there are several common methods.
One is to use 3-cyanopyridine as the starting material. First, 3-cyanopyridine can be reduced to aminomethyl under suitable reaction conditions, such as in anhydrous ether and other inert solvents, and carefully react at low temperature. The cyano group can be reduced to aminomethyl to obtain 3- (aminomethyl) pyridine. This reaction requires attention to the amount of reducing agent and the reaction temperature to prevent side reactions such as excessive reduction.
Second, 3-pyridine formaldehyde can be started. 3- (aminomethyl) pyridine can be obtained by reacting 3-pyridine formaldehyde with urotropine under acidic conditions to form the corresponding quaternary ammonium salt, and then hydrolyzing. In this process, the conditions for controlling acidic hydrolysis are quite critical, and too strong or too weak acidity may affect the yield and purity of the reaction.
Third, 3-halogenated pyridine is used as the raw material. The 3-halopyridine is reacted with magnesium metal to form a Grignard reagent, which is then reacted with formaldehyde to produce 3-pyridyl methanol, which is then oxidized to 3-pyridyl formaldehyde. The subsequent steps are the same as the above method of preparing 3-pyridyl formaldehyde, or the 3-halopyridine is reacted with sodium cyanide to introduce a cyano group, and then the cyano group is reduced to aminomethyl. This route has many steps, and each step of the reaction needs to be carefully controlled to ensure the quality and yield of the final product.

3 - (aminomethyl) pyridine, its physical properties are as follows:
This substance is mostly liquid at room temperature, clear and transparent in appearance, with a special smell, pungent smell and obvious alkaline smell. Its boiling point is between 194 and 196 degrees Celsius. If placed in an open container, with the increase of temperature, the thermal motion of the molecules intensifies, and at this boiling point, it will vaporize into a gaseous state and escape. The melting point is around -20 degrees Celsius. When the ambient temperature drops to this point and below, the substance changes from liquid to solid, and the molecular arrangement tends to be ordered from disorder, forming a relatively regular lattice structure. < Br >
Its density is about 1.05 - 1.07 g/cm ³. When mixed with water, it will slowly sink because its density is slightly higher than that of water. It has a certain solubility in water. Because its molecular structure contains nitrogen atoms, it can form hydrogen bonds with water molecules and improve dispersion in water. In organic solvents such as ethanol and ether, the solubility is higher. Due to the principle of similar miscibility, it is easier to disperse uniformly with the force between organic solvent molecules.
In addition, 3 - (aminomethyl) pyridine has a specific refractive index, and when light passes through, the propagation direction changes to a fixed degree. This property has considerable application value in the fields of optical analysis and purity detection. Its surface tension also has a corresponding value, which affects the behavior of the liquid surface and the interfacial interaction with other substances.

For 3- (aminomethyl) pyridine, there are many things to pay attention to during storage and transportation, and they should be handled with caution.
This substance has certain chemical activity. When storing, the first environment should be selected. It should be placed in a cool, dry and well-ventilated place, away from fire and heat sources, so as to avoid changes in its properties or dangerous reactions due to improper temperature and humidity. Because of its sensitivity to air and moisture, the storage container must be tightly sealed to prevent excessive contact with air and moisture and deterioration.
Furthermore, during transportation, do not be slack. It is necessary to choose suitable packaging materials according to their chemical characteristics. The packaging should be sturdy and airtight, which can effectively resist vibration, collision and friction, and ensure the integrity of the material during transportation. At the same time, the transportation vehicle should also be equipped with corresponding fire protection equipment and leakage emergency treatment equipment to prevent accidents. And the transportation process must strictly abide by relevant regulations and standards, drive according to the specified route and time, and avoid densely populated areas and high temperature periods.
Those who operate this substance should have professional training and be familiar with its characteristics and emergency treatment methods. Storage and transportation places should post clear warning signs to remind personnel to operate with caution. In this way, it is necessary to ensure the safety of 3- (aminomethyl) pyridine during storage and transportation, and avoid disasters.
