What is the market price of Naphthylene-1,6-Disulfonic Acid Sodium Salt?

Naphthalene-1,6-disulfonic acid disodium salt. The price of this product in the city is difficult to determine due to various reasons. Looking at the method of "Tiangong Kaiwu", the price of various products in the past varied according to time, place, quality and supply and demand. The same is true of naphthalene-1,6-disulfonic acid disodium salt today.
Its price is first related to quality. The superior is pure and high, and the miscellaneous is less, and it must be more expensive than the inferior. The production is fine and coarse, and the quality of the material is the key to quality. Those who are refined and have good raw materials are the most sought in the city, and the price is high.
The origin and transportation are also heavy. If the product is close to the city and the transportation cost is saved, the price is appropriate. If the production is long, the road insurance is difficult, and the fee is added to the price, the price will definitely rise.
The situation of supply and demand is also the cardinal of the price. When the demand is strong, the merchants compete for goods, and the price will rise; if the supply is excessive, the stock of goods is difficult to sell, and the price will fall.
Also, the competition in the city also determines the price. There is a lot of competition, in order to attract customers, or to cut prices; those who occupy the market, the price can be controlled.
Although it is difficult to determine the price, looking at the state of the market, considering the quality, land, supply and demand and the reasons for the competition, the price range can be known. Roughly speaking, in today's market, the price per kilogram may be between tens of yuan and hundreds of yuan, but this is only an approximation. To determine the price, we must carefully consider the real-time market conditions.

What are the storage conditions for Naphthylene-1,6-Disulfonic Acid Sodium Salt?

Naphthalene-1,6-disulfonic acid, sodium salt, there are three most important ways to store it. First, it should be placed in a cool place. This medicine is prone to change its properties when heated, and heat may cause decomposition and deterioration. Hidden in a cool place, the temperature is always kept moderate, so as to avoid damage to its quality due to heat.
Second, it must be in a dry environment. If this thing is in a humid place, it is easy to absorb moisture and cause all kinds of changes. Moisture can cause it to agglomerate, or promote it to chemically react with moisture, resulting in a great reduction in efficacy. Therefore, choose a dry place to hide it, so that it can be preserved for a long time.
Third, it needs to be protected from light. Light can also affect its stability. Under light, or a chemical reaction that prompts light, the composition changes. Therefore, it is appropriate to store it in an opaque container and hide it in a dark place to protect it from light disturbance.
In summary, Tibetan naphthalene-1,6-disulfonic acid, sodium salt, should be selected in a cool, dry and dark place to ensure its stability and purity, and can be used for a long time.
