There are various ways to synthesize amino-3-nitropyridine. One is to use pyridine as the starting material, introduce nitro groups into the pyridine ring through nitration reaction, and then convert the nitro groups into amino groups through reduction reaction. Specifically, in the nitration step, pyridine can be co-placed with mixed acids of nitric acid and sulfuric acid, and the reaction temperature and time can be controlled to make pyridine nitrate accurately at 3 positions to obtain 3-nitropyridine. Subsequently, suitable reducing agents, such as iron powder, zinc powder, etc., are selected to reduce 3-nitropyridine in an acidic medium to obtain the target product, amino-3-nitropyridine.
The second method can be started from pyridine derivatives containing amino groups and nitro groups, and achieved by appropriate functional group conversion. For example, first prepare a pyridine derivative with a specific substituent, which contains functional groups that can be converted into amino groups and nitro groups, and then carry out the corresponding reactions in sequence to convert the functional groups into amino groups and nitro groups one by one, and finally synthesize amino-3-nitropyridine. However, this approach needs to be carefully studied for each step of the reaction conditions to ensure the selectivity and yield of the reaction.
Another method can use the coupling reaction catalyzed by transition metals. The target molecule is formed by the coupling reaction of pyridine derivatives containing suitable leaving groups and reagents containing amino or nitro groups under the action of transition metal catalysts such as palladium catalysts. This method requires careful screening of catalysts, ligands and reaction solvents to achieve efficient and highly selective synthesis. All these synthesis methods have advantages and disadvantages. In practical application, the choice needs to be weighed according to many factors such as the availability of raw materials, the feasibility of reaction conditions, the purity and yield of the product.

3-Amino-3-nitropyridine, when it is stored and transported, all kinds of matters must be paid attention to. This is a chemical substance, its nature is different, and if it is slightly careless, it may cause disaster.
When it is stored, the first environment is heavy. It should be placed in a cool, dry and well-ventilated place, away from direct sunlight, to prevent decomposition by heat and cause danger. Temperature and humidity should also be carefully controlled to avoid deterioration. Furthermore, it must be separated from other substances, especially those with oxidation, reduction or acidic and alkaline substances, to avoid chemical reactions, damage its quality, or even cause violent reactions, endangering safety.
When shipping, the packaging must be tight. A suitable container should be used to keep it stable and not damaged by vibration and collision. The transporter must also undergo professional training to be familiar with the properties of this object and know how to deal with it in case of emergency. Always check the complete damage of the package on the way. If there is any leakage, take proper measures quickly and do not slack off.
In addition, whether it is stored or shipped, detailed records must be kept, recording the quantity, entry and exit time and condition. Everyone should also strictly abide by the relevant regulations and must not violate them. In this way, the safety of 3-amino-3-nitropyridine storage and transportation can be avoided.
