In summary, 2 - (aminomethyl) pyridine, with its unique chemical structure, occupies an important position in many fields such as drugs, materials, catalysis, etc., providing key support for technological innovation and development in various fields.

2 - (aminomethyl) pyridine, its physical properties are as follows:
This substance is mostly liquid at room temperature, and it has a colorless to light yellow appearance. If it is pure, it is clear and transparent. Its odor is unique, with a pungent and irritating smell, and it is uncomfortable to smell. 2 - (aminomethyl) pyridine has a high boiling point, about 195-198 ° C. This property allows it to change from liquid to gaseous at higher temperatures. The melting point is relatively low, around -20 ° C, which means that the temperature is slightly higher than this, and it is liquid.
Its density is slightly larger than that of water, about 1.05-1.08g/cm ³, so if mixed with water, it will sink underwater. 2- (Aminomethyl) pyridine can be miscible with water and many organic solvents such as ethanol and ether. This is because the molecular structure contains polar groups, which can form hydrogen bonds or have similar polarities with water and some organic solvents, resulting in good solubility.
In addition, the substance is hygroscopic and easily absorbs water vapor in humid air. When storing, pay attention to moisture protection. Its vapor is heavier than air and accumulates in low places. It may pose a safety hazard in poorly ventilated environments.

2 - (aminomethyl) pyridine, its chemical properties are of great interest. This substance contains a pyridine ring and an aminomethyl group, and its structure is unique, so it has multiple chemical properties.
As far as alkalinity is concerned, because the nitrogen atom of the pyridine ring has lone pairs of electrons, it has a certain alkalinity and can form a salt with an acid. The amino group of the aminomethyl group is also alkaline, and the synergy between the two makes its alkalinity not to be underestimated. In case of strong acids, such as hydrochloric acid, it can react quickly to form corresponding salts, which can be used in organic synthesis to achieve separation and purification of substances.
Its nucleophilicity is also an important property. The nitrogen atom of the aminomethyl group is rich in electrons and has strong nucleophil In the presence of halogenated hydrocarbons, nucleophilic substitution is easy to occur. Nitrogen atoms attack the carbon-halogen bonds of halogenated hydrocarbons, and the halogen atoms leave to form new carbon-nitrogen bonds. This allows complex organic molecular structures to be constructed, which is of great significance in the field of drug synthesis.
In addition, 2- (aminomethyl) pyridine also has reductive properties. The hydrogen atom of aminomethyl can be oxidized under certain conditions, and the pyridine ring may also participate in the oxidation reaction. For example, under the action of strong oxidants, the pyridine ring may open the ring, or the aminomethyl group may be oxidized to other functional groups such as carboxyl groups. This property needs to be carefully considered in the design of organic synthesis routes in order to achieve the desired reaction goals. < Br >
Due to its structure containing nitrogen atoms and hydrocarbon groups, 2- (aminomethyl) pyridine can coordinate with a variety of metal ions to form stable complexes. In the field of catalysis, such complexes are often used as catalysts. With their unique electronic structure and spatial configuration, they enhance the activity and selectivity of catalytic reactions and provide efficient catalytic pathways for many organic reactions.

The synthesis of 2 - (aminomethyl) pyridine has been known for a long time and is described in detail below.
First, 2-pyridine formaldehyde is used as the starting material. This aldehyde and methylamine undergo a reductive amination reaction under appropriate catalyst and reaction conditions. Methylamine provides an amino group, and the catalyst promotes the smooth progress of the reaction. The aldehyde group is reduced and connected to the amino group to form 2 - (aminomethyl) pyridine. This reaction condition is mild and relatively simple to operate. However, the purity and cost of the raw material 2-pyridine formaldehyde have a great impact on the synthesis.
Second, it is started from 2-chloromethylpyridine. The nucleophilic substitution reaction occurs between 2-chloromethylpyridine and ammonia, and the chlorine atom is replaced by the amino group in ammonia to obtain the target product. The raw materials in this route are relatively easy to obtain, but the reaction conditions, such as temperature and ammonia dosage, need to be controlled in the reaction to prevent side reactions from occurring and causing impure products.
Third, pyridine is used as raw material and prepared through multi-step reaction. First, pyridine is substituted at a specific position, a suitable functional group is introduced, and then a series of conversions are carried out to finally obtain 2- (aminomethyl) pyridine. Although this route has many steps, the raw material pyridine has a wide range of sources. If the reaction conditions of each step are properly optimized, it is also a feasible method. < Br >
The methods for synthesizing 2- (aminomethyl) pyridine have their own advantages and disadvantages, and the appropriate method should be selected according to the actual situation, such as the availability of raw materials, cost considerations, and product purity requirements.

2-%28Aminomethyl%29pyridine is 2 - (aminomethyl) pyridine, which is an organic compound. When storing and transporting, many aspects need to be carefully paid attention to.
For storage, the first environment should be selected. It should be placed in a cool and well-ventilated place, because the substance is prone to chemical changes when heated, or even cause danger. Keep away from fire and heat sources to prevent the risk of explosion. Because of its flammability, it may encounter open flames, hot topics or violent reactions.
Furthermore, the storage container must be sealed. 2 - (aminomethyl) pyridine is exposed to air, or interacts with oxygen, water vapor, etc., resulting in quality deterioration. It is commonly used to store in sealed glass bottles or metal drums to ensure that the container does not leak. At the same time, the storage area should be equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment for emergencies.
As for transportation, it is necessary to ensure that the packaging is complete and safely loaded before transportation. Packaging should comply with relevant regulations to prevent damage and leakage of containers during transportation. During transportation, keep away from fire and heat sources, and prevent sun exposure and rain. Transportation vehicles should also be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment. Transportation personnel need to be professionally trained, familiar with the dangerous characteristics and emergency treatment methods of 2 - (aminomethyl) pyridine, pay close attention to the condition of the goods during transportation, and deal with any abnormalities in a timely manner.
In short, the storage and transportation of 2 - (aminomethyl) pyridine requires safety and strict operation in accordance with regulations to ensure the safety of personnel and the environment.
