The synthesis method of 8-hydroxy-5-nitrosoquinoline has been recorded in various books throughout the ages. The methods can be roughly described as follows.
First, using quinoline as the group, through the technique of nitrification, can open the way for synthesis. Put quinoline in a suitable reaction system, integrate specific nitrifying reagents, and adjust the temperature and time of the reaction. Nitric acid, mixed acid, etc. are often used for nitrification. Under moderate temperatures, let them interact, and the quinoline molecule obtains the substitution of nitro, which is a problem of isomerism at this time or in the raw position. It is necessary to carefully adjust so that the nitro falls in the fifth position of the quinoline ring.
Second, it is changed from 5-nitroquinoline. 8-hydroxy-5-nitrosoquinoline can be obtained by reduction of 5-nitroquinoline. The reduction method can be selected as the way of catalytic hydrogenation. Appropriate catalysts, such as palladium carbon, are used in the environment where the hydrogen source is sufficient and the pressure is moderate, so that the nitro group is gradually reduced to the nitroso group, while taking into account the protection and generation of hydroxyl groups. Or chemical reduction reagents, such as low-priced metal salts, can be used to achieve this transformation according to a specific reaction mechanism. However, when using chemical reagents, the selectivity and controllability of the reaction must be carefully controlled to prevent excessive reduction or other side reactions from breeding.
Third, using raw materials containing hydroxyl groups and nitro precursors, the method of cyclization and condensation. Find a benzene ring or pyridine ring derivative with suitable substituents, and make it in the presence of a specific condensation agent and catalyst, through condensation and cyclization, construct quinoline parent nuclei, and realize the introduction of 8-hydroxy and 5-nitroso groups at the same time. This path requires a lot of control over the design of raw materials and reaction conditions, but if properly controlled, it is also a good method for synthesis.
All these synthesis methods have advantages and disadvantages. The purpose of synthesis can be achieved only after careful selection according to actual needs, availability of raw materials, difficulty of reaction and many other factors.

8-Hydroxy-5-nitrosoquinoline is also a chemical substance. During storage and transportation, many matters need to be paid attention to carefully.
Its nature or instability, heat, light or can cause decomposition and deterioration, so when storing, it is advisable to choose a cool, dry and dark place. If the temperature is too high, it can accelerate its reaction and damage its quality. Therefore, the warehouse temperature should be controlled within a suitable range, usually not exceeding 30 ° C. And it must be kept away from fire and heat sources to prevent unexpected changes.
8-Hydroxy-5-nitrosoquinoline may be toxic and corrosive to a certain extent, and it is potentially dangerous to the human body and the environment. When storing, make sure that the container is well sealed to avoid leakage. If it accidentally leaks, or contaminates the environment, endangering all living beings. When transporting, it is also necessary to strictly abide by relevant regulations, and the packaging must be tight to prevent leakage due to vibration and collision. The packaging materials used should be able to withstand its corrosion, and the label is clear, indicating its dangerous characteristics.
