The first to bear the brunt is the complexity of the preparation process. If the preparation process requires multiple steps of reaction, and the reaction conditions are strictly controlled, the reagents or catalysts used are very expensive, the cost will rise, and the market price will also rise. On the contrary, if the preparation process is simple, the cost is controllable, and the price may be close to the people.
Furthermore, the market supply and demand situation is also a key factor. If the demand for 1-bromo-2,6-difluoro-4-iodobenzene is strong in many industries and the supply is limited, the supply will exceed the demand, and the price will surely rise. If the market demand is weak and the supply is excessive, there will be downward pressure on the price.
In addition, fluctuations in the price of raw materials will also affect the cost and price of 1-bromo-2,6-difluoro-4-iodobenzene. If the price of raw materials rises, its production cost will increase, and the market price may also increase.
From the past market conditions, the prices of such fine chemicals vary greatly. Those with high purity and high quality may cost hundreds of yuan per gram; while those with slightly lower purity and average quality may cost tens of yuan per gram. However, this is only a rough range, and the actual price may fluctuate widely at different times and different suppliers due to the above factors. Therefore, in order to know the exact market price, it is necessary to consult the relevant suppliers or market survey agencies in detail to obtain the latest and accurate price information.
