Methyl-5-bromopyridine-3-carboxylic acid ester, the price of this product in the chemical market is quite variable for many reasons.
The first to bear the brunt is the cost of raw materials. 5-bromopyridine-3-carboxylic acid and methanol are the key raw materials for synthesizing this product. If the supply of raw materials is in short supply or the market demand surges, its price will rise, which in turn will cause the production cost of methyl-5-bromopyridine-3-carboxylic acid ester to rise, and the price will also rise.
Furthermore, the difficulty of the production process is closely related to the cost. If the synthesis process is complicated, special equipment, catalysts, or multi-step reactions or strict reaction conditions are required, all of which will increase production costs and eventually increase the price of the product. On the contrary, simple and efficient processes may reduce costs and make prices more affordable.
The relationship between market supply and demand is also the main reason for the price. If at some time, this product is in strong demand in the fields of medicine, pesticides, etc., but the production supply is difficult to increase rapidly, and the supply is in short supply, the price will rise. On the contrary, if the market is saturated and the supply exceeds the demand, the manufacturer may reduce the price and promote it.
In addition, different manufacturers have different cost control due to different technical levels, economies of scale, and management capabilities, and the price set is also different. Large factories may be able to reduce unit costs by virtue of their scale advantages, and their pricing may be more competitive.
Overall, the market price of methyl-5-bromopyridine-3-carboxylate can range from hundreds of yuan per kilogram to more than 1,000 yuan. It is difficult to make a conclusion. It needs to be studied in detail according to the current market situation.

The existence of methyl-5-bromopyridine-3-carboxylic acid ester depends on its properties. This material is sensitive, and it should be avoided from water and fire, and it should be far away from things that can respond to it.
This medicine should be stored in a cool and dry place, and the temperature should not be high to prevent it from changing. If the cover temperature is high, it may cause it to change, or cause it to change, which will damage its quality. And it should be placed in dark places. Light can also induce it to change, and keep its quality pure. Light is a taboo.
And it must be solid when sealed, and it will prevent the invasion of air and water.
