In the field of medicine, or used to create drugs with specific biological activities; in the field of pesticides, or to help develop efficient and low-toxic pesticides.
Its price is determined by a variety of factors. The first one is the market supply and demand situation. If the market demand is strong and the supply is limited, such as the production is limited due to the complex production process and the scarcity of raw materials, the price will easily go up; on the contrary, if the market demand is weak and the supply is sufficient, the price may decline.
Furthermore, the production cost has a great impact. The cost of raw materials is a key part, and the fluctuation of raw material prices is directly related to the cost of products. If the price of raw materials rises, the production cost increases, and the selling price will also increase accordingly. The complexity of the production process also has an impact. The complexity of the production process requires higher technology and equipment investment, and the cost rises, and the product price naturally rises.
In addition, quality is also an important factor in determining the price. High-purity, high-quality products, due to the difficulty of production, can meet high-end demand, and the price is often higher; while those with lower quality, the price may be relatively low.
According to past market conditions, the price of this compound fluctuates widely. In some cases of ordinary quality and sufficient supply, the price per kilogram may be several hundred yuan; if it is high purity, special specifications and in short demand, the price per kilogram may reach several thousand yuan. However, the market is unpredictable, with fluctuations in raw material prices, changes in policies and regulations, and the emergence of new production technologies. Therefore, to know the exact market price, you need to pay attention to the chemical product trading platform in real time and consult relevant suppliers to obtain accurate price information.
