What is the market price of 5-iodo-2-methoxy-3- (trifluoromethyl) pyridine?
I look at the market price of "5 - iodo - 2 - methoxy - 3 - (trifluoromethyl) pyridine", which is in the field of fine chemicals, and its price often varies due to various reasons.
In terms of its purity, if the purity is extremely high, it is close to 99%, which is suitable for high-end scientific research experiments, and the price must be high. Because of the purification to such a degree, the process is complicated, and it requires exquisite technology and high cost, such as layer-by-layer screening and delicate separation methods, the price per gram may reach hundreds of gold.
Furthermore, the purchase volume is also the key. If it is used in small quantities by scientific research institutions to meet the needs of the experiment, the merchant may price it higher because of the small quantity. However, if it is a large pharmaceutical company, the demand is massive, reaching several kilograms or even several tons. Due to economies of scale, the unit price may be reduced.
In addition, the market supply and demand situation also affects its price. If this product is popular in research and development, and many institutions compete for it, and the supply is in short supply, the price will rise; if the research and development trend changes, the demand will drop sharply, the supply will exceed the demand, and the price may decline.
And the different manufacturers also lead to price differences. Well-known large factories have excellent equipment and strict quality control. The cost may be high, and the price is also high; while some small factories, although the cost is low, the quality may be unstable.
As for the exact price, it is difficult to hide it. You need to consult chemical raw material suppliers or professional chemical product trading platforms in order to obtain near-real-time and accurate prices.
