The price range of 7-bromo-1H-imidazolo [4,5-b] pyridine on the market is difficult to determine. The price of these compounds often varies due to various factors.
First, purity is the key. If the purity is extremely high and almost flawless, the price will be high; on the contrary, the purity is slightly inferior, and the price may be slightly lower. For example, the price of high-purity products used in the research and development of fine pharmaceuticals is higher than that of industrial preliminary purification.
Second, the purchase quantity also has an impact. Bulk purchase, due to the scale effect, the unit price may be discounted; if only a small amount is purchased for laboratory initial testing, the merchant may price it higher due to operating cost considerations.
Third, the supply and demand relationship between market conditions affects the price. If the demand is strong for a while and the supply is limited, the price will rise; if the supply exceeds the demand, the price may drop.
Fourth, the source route is different, and the price is also different. Produced by well-known large factories with strict quality control, the price may be higher than that of small factory products. And importers, due to tariffs, transportation and other fees, the price is often higher than that of local producers.
Looking at the market, the price per gram may range from tens of yuan to hundreds of yuan. If it is scientific research grade high purity, it may be more than 100 yuan per gram; if it is industrial grade and the purity is slightly lower, it may be tens of yuan per gram. However, this is only an approximate estimate. To obtain an accurate price, you need to consult the chemical supplier in detail, subject to real-time market conditions.
