I look at this "Methyl 5 - bromo - 1H - pyrrole - 2 - carboxylate", which is a chemical substance, that is, methyl 5 - bromo - 1H - pyrrole - 2 - formate. Its market price is difficult to determine. Due to the volatile market conditions, the price is affected by many factors.
First, the price of raw materials, if the raw material for preparing this methyl ester, its price rises and falls, the price of this methyl ester will also change. If the raw material is rare, its manufacturing cost will be high, and the price will also rise; if the raw material is easy to obtain and cheap, the cost will decrease and the price will also decrease.
Second, the situation of supply and demand, if the market demand for this product is strong, but the supply is small, the price will rise; if the demand is weak and the supply is large, the price will fall. If the demand for methyl ester in a certain industry increases sharply at a certain time, but the supply of producers is limited, the price will rise.
Third, the manufacturing process is simple, if the manufacturing requires exquisite and complex processes, time-consuming and labor-intensive, and requires a lot of manpower and material resources, the cost will be high and the price will be high; if the process is simple, the cost will decrease and the price will be low.
Fourth, the competition of producers also has an impact. If there are many producers, in order to compete for market share, they may win by price, resulting in lower prices; if there are few producers, the trend of monopoly will gradually become, and prices may rise.
Therefore, in order to know the exact market price, you need to often look at the chemical market conditions, or consult chemical product suppliers, in order to obtain a more accurate price.

Methyl-5-bromo-1H-pyrrole-2-carboxylic acid ester is one of the organic compounds. Its storage conditions are quite important, which is related to the quality and stability of this compound.
This compound should be stored in a cool and dry place. Cover a cool place to reduce its chemical reaction rate caused by excessive temperature and avoid its decomposition or deterioration. In a dry environment, it can prevent it from contacting with water vapor and preventing adverse reactions such as hydrolysis. Water vapor is often the cause of deterioration of many organic compounds, so it is crucial to keep it dry.
Furthermore, it needs to be stored in a well-ventilated place. Ventilation allows possible volatiles to dissipate in time, without accumulation causing danger, and can also maintain the fresh air in the storage environment, which is beneficial for the preservation of the compound.
And should be kept away from fire sources, heat sources and oxidants. Fire sources and heat sources are prone to combustion or violent reactions, while oxidants have strong oxidizing properties. When storing, also pay attention to sealing. Sealing can prevent the intrusion of external air, water vapor and impurities, and maintain the purity and stability of the compound. It is only proper to hold it in a suitable container to ensure that the material of the container does not chemically react with the compound. In this way, methyl-5-bromo-1H-pyrrole-2-carboxylate can maintain good quality and chemical properties during storage.
