1-Phenylazo-2-Naphthol-6, 8-Disulphonicacid, Disodium salt What are the precautions when storing

1-Phenylazo-2-naphthol-6,8-disulfonic acid disodium salt, this is a chemical substance. When storing, there are several precautions to be paid attention to.
First, it should be placed in a cool and dry place. Because it is in a humid and warm place, it may be susceptible to deliquescence, causing its chemical properties to change. For example, if stored in a warehouse with high humidity and high temperature, there may be caking and other conditions that affect its quality and use.
Second, it should be kept away from fire sources and strong oxidants. This substance may be flammable to a certain extent, and there is a risk of burning in case of open flames and hot topics; and strong oxidants come into contact with it, or cause violent chemical reactions, even the risk of explosion. It is like being in a place full of fire and dangerous chemicals, which may trigger danger at any time.
Third, the storage place needs to be well ventilated. If the ventilation is poor, its volatile gas will accumulate, which will not only damage the environment, but also endanger personal health, or cause respiratory discomfort.
Fourth, it should be placed separately from other chemicals. Especially acids and alkalis, which are mixed with them, are prone to chemical reactions, causing them to deteriorate and fail. If people of different characters coexist in the same room, it is easy to cause conflicts if their habits are different.
Fifth, it needs to be properly stored in a sealed container. This can prevent it from being in excessive contact with air, slow down the rate of oxidation and other reactions, and maintain its chemical stability. If the seal is not good, it seems that the door is wide open, and external factors can easily invade and destroy its original properties.
Therefore, store 1-phenylazo-2-naphthol-6,8-disulfonate disodium salt, and follow the above things carefully to ensure its safety and quality.
