The synthesis of 1-methylpyrrole-2-formonitrile is not detailed in the ancient book "Tiangong Kaiwu", but today's chemical technology can find a way. Usually there are the following methods.
First, 1-methylpyrrole is used as the starting material. First, it is reacted with a suitable halogenating agent, such as halogenated sulfoxide, under appropriate conditions, and a halogen atom is introduced at the 2-position of the pyrrole ring to form a halogenated 1-methylpyrrole. Then, the halogen is reacted with a cyanizing agent, such as potassium cyanide or sodium cyanide, in the presence of a phase transfer catalyst, in a suitable organic solvent. In this process, attention should be paid to the control of reaction temperature and time. Generally, the temperature should be within a moderate range to avoid side reactions caused by too high. The time also needs to be precisely controlled to promote the successful replacement of cyanyl groups with halogens to obtain 1-methylpyrrole-2-formonitrile.
Second, pyrrole-2-formonitrile can be used. The nitrogen atom of the pyrrole ring is methylated first. Commonly used methylation reagents include iodomethane or dimethyl sulfate. Under alkaline conditions, such as the presence of bases such as potassium carbonate, react in a suitable solvent. The alkali can promote the hydrogen of the pyrrole nitrogen atom to leave, and then undergo nucleophilic substitution reaction with the methylating agent to complete 1-methylation, and finally obtain 1-methylpyrrole-2-formonitrile. This process requires attention to the amount of alkali and the anhydrous requirements of the reaction environment to prevent side reactions.
Or, the strategy of constructing a pyrrole ring by using a multi-step reaction. Taking an organic compound containing a suitable substituent as the starting material, through a series of reactions such as cyclization and substitution, a pyrrole ring is formed first, and methyl and cyano groups are introduced at the same time in suitable steps to finally synthesize 1-methylpyrrole-2-formonitrile. Although there are many steps in this path, each step requires fine regulation of the reaction conditions to achieve the expected product. In short, the synthesis method needs to be based on the actual situation, weigh the advantages and disadvantages of each method, and choose carefully.

1-Methylpyrrole-2-formonitrile is an organic chemical substance. When storing and transporting, many things must be paid attention to.
When storing, the first environment should be selected. It should be placed in a cool, dry and well-ventilated place, because the substance may be sensitive to temperature and humidity. If the environment is humid or causes it to deteriorate by moisture, it will affect the quality and chemical properties; if the temperature is too high, it may also cause chemical reactions, resulting in decomposition of substances or other changes. And it should be kept away from fires and heat sources, because it is flammable to a certain extent, in case of open flames, hot topics or the risk of combustion and explosion.
Furthermore, storage needs to be classified. Do not mix with oxidizing agents, acids, alkalis, etc. Because 1-methylpyrrole-2-formonitrile is chemically active, contact with the above substances, or violent chemical reaction occurs, which may cause danger.
In terms of transportation, the packaging must be tight. Make sure that the packaging container is not at risk of leakage to prevent the substance from leaking outside and causing harm to the environment and personnel. During transportation, also keep away from heat sources and fires to prevent direct sunlight. Transportation vehicles also need to be equipped with corresponding fire protection equipment and leakage emergency treatment equipment. In the event of an accident, they can respond in time. Transportation personnel should also be familiar with the characteristics of the substance and emergency treatment methods. During transportation, pay close attention to the condition of the goods. If there is any abnormality, take immediate measures. In this way, the safety of 1-methylpyrrole-2-formonitrile during storage and transportation is guaranteed.

The price trend of 1-methylpyrrole-2-formonitrile is related to various reasons. This is one of the fine chemicals, and the price of its price often depends on the state of supply and demand, the price of raw materials, the difficulty of the production process and the competition of the market.
Let's talk about supply and demand first. If the market is prosperous, and there are many people who use it, it is needed in the fields of medicine, pesticides or materials, and if there are few suppliers, the price will rise. On the contrary, if you want to dilute and supply more, the price will tend to drop.
The price of raw materials is also heavy. The production of 1-methylpyrrole-2-formonitrile depends on all kinds of raw materials. If the price of raw materials increases, such as methylating agents, cyanidating agents, etc., the cost will increase, and the price will also go up. If the price of raw materials falls, the cost will decrease, and the price may decrease.
The difficulty of the process also affects its price. If the production requires harsh conditions, such as high temperature, high pressure, high purity raw materials, or complex reaction steps, the technical requirements are high, the amount of production is small, and the price will be high. If the process is gradually simplified, the yield will increase, and the price will fall.
Furthermore, the competition in the market is also. If there are many people who want to compete for the market with this product, they must take the best price as a policy, and the price will decline. If the industry is small and has the tendency to monopolize, the price will be controllable and higher.
In the past few years, looking at the market, the price may fluctuate. At first, due to the expansion of new uses, the demand for more supply did not respond quickly, and the price showed an upward trend. Later, due to the advance of technology, the yield increased, and new producers entered, the supply gradually increased, and the price fell slightly. However, if the price of raw materials suddenly rises, or the regulation of the government changes, or the natural and man-made disasters cause production to be blocked, the price will rise again.
In conclusion, the market price trend of 1-methylpyrrole-2-formonitrile is the result of the interaction of supply and demand, raw materials, manufacturing processes, and competing factors. To know the truth, we should always observe the changes in the market and observe the movements of various factors.
