The synthesis method of 6-nitro-1,2-naphthalene oxadiazole-4-sulfonic acid, although the ancient book "Tiangong Kaiwu" does not directly describe this material, it can be found by analogy with its process idea.
Synthesize such compounds in the past, or start from the selection of raw materials. Select raw materials containing naphthalene rings, such as naphthol derivatives, because they have the basis for constructing the structure of naphthalene oxadiazole. After nitrification, nitro groups are introduced.

Then, construct oxadiazole rings. Or condensate nitrogen-containing reagents with specific carbonyl compounds. For example, compounds containing amino groups and carboxyl groups are dehydrated and cyclized under suitable catalyst and reaction conditions to form this heterocyclic structure. During the process, the properties of the solvent, the degree of temperature, and the time of the reaction are all critical. If the polarity of the solvent is not good, the reaction is difficult to go forward, the temperature is too high or the side reactions are clustered. The introduction of
sulfonic acid groups is often done with sulfonating reagents, such as fuming sulfuric acid. This step should also be carefully regulated so that the sulfonic acid groups fall into the 4 position. When sulfonating, pay attention to the acidity of the reaction system and the monitoring of the reaction process, which can be observed by thin-layer chromatography.

6-Nitro-1,2-Naphthoxydiazole-4-Sulfonic Acid What are the precautions in storage and transportation
6-Nitro-1,2-naphthalene-oxadiazole-4-sulfonic acid, during storage and transportation, it is necessary to pay attention to many matters.
This compound has specific chemical properties and is the first choice for storage. It should be placed in a cool, dry and well-ventilated place. If it is in a warm and humid environment, or due to the influence of moisture and temperature, its chemical properties change, and even cause reactions such as decomposition, which will damage its quality and utility.
Furthermore, it needs to be separated from oxidizing, reducing and basic substances. Because there are nitro groups, sulfonic acid groups, etc., in case of oxidizing substances, or violent oxidation reaction; in case of reducing substances, or reduction reaction occurs; and sulfonic acid groups are acidic, and in case of alkaline substances, it is easy to neutralize, which will cause its chemical composition and properties to change.
When transporting, the packaging must be strong and tight. Choose suitable packaging materials, such as containers with good sealing properties, to prevent leakage. If leakage occurs during transportation, it will not only damage the goods themselves, but also may cause pollution to the environment, and may endanger the safety of transporters.
