To prepare 1H-pyrrole-3-carboxylic acid, 2,5-dimethyl-, ethyl ester, you can follow the following method.
Take 2,5-dimethylpyrrole as the starting material first. It is dissolved in an appropriate solvent, and an inert solvent such as dichloromethane can often be used. In this solution, slowly add an appropriate amount of acylating agent, such as oxalyl chloride or phosphorus trichloride, to acylate the 3 positions of pyrrole to obtain 2,5-dimethyl-1H-pyrrole-3-formyl chloride. This step requires attention to the reaction temperature and feeding rate to prevent side reactions.
times, the obtained 2,5-dimethyl-1H-pyrrole-3-formyl chloride is mixed with ethanol, and an appropriate amount of acid binding agent, such as pyridine or triethylamine, can be added to promote the esterification reaction. This reaction also needs to be controlled at temperature to make the reaction proceed smoothly. After the reaction is completed, the separation and purification methods, such as vacuum distillation, column chromatography, etc., remove unreacted substances and by-products, and obtain a relatively pure 2,5-dimethyl-1H-pyrrole-3-carboxylic acid ethyl ester.
In another way, the condensation reaction between 2,5-dimethyl pyrrole and diethyl malonate under the catalysis of strong bases such as sodium ethanol can first occur to generate the corresponding pyrrole-3-carboxylic acid ethyl ester derivatives. After appropriate decarboxylation, the target product can also be obtained. In this process, the amount of strong base and the control of the reaction time are quite important, and improper product impurity or low yield can be easily caused. In short, according to the above steps and careful operation, 1H-pyrrole-3-carboxylic acid, 2,5-dimethyl-, ethyl ester can be prepared.

Today I have a question, what is the market price of 1H-pyrrole-3-carboxylic acid, 2,5-dimethyl-, ethyl ester. This is a chemical substance, and to know its price, you need to look at various reasons.
The price of chemical materials in the past often changed depending on the number of sources. If the raw materials of this substance are easy to obtain, widely distributed in origin, and abundant in output, the price may tend to be simple. On the contrary, if the raw materials are rare, difficult to collect, and the output is scarce, the price will be high.
Furthermore, the difficulty of preparation also depends on the price. If the preparation method is cumbersome, requires a lot of rare reagents, goes through many complicated processes, and requires fine operation and high-end equipment, then the cost will increase greatly, and its price in the market will also be high.
And the state of market supply and demand is also the key. If many industries have strong demand for it, but the supply is limited, the demand exceeds the supply, and the price will rise; if the demand is small and the supply exceeds the demand, the price may be lower.
In addition, changes in the current situation and policy regulations can also affect the price. Such as tariff adjustment and environmental protection orders, the cost can increase or decrease, which in turn affects the price.
However, I don't know the specific production, sales, supply and demand of 1H-pyrrole-3-carboxylic acid, 2,5-dimethyl-, ethyl ester, etc. It is difficult to determine its market price. To get an accurate price, when you check the chemical market information in detail, consult industry experts, or know the general idea.

1H-pyrrole-3-carboxylic acid, 2,5-dimethyl-, ethyl ester. When storing and transporting, you need to pay attention to many matters.
First, when storing, place it in a cool and dry place. If it is in a humid environment, or the quality changes due to moisture absorption. Remember the ancient cloud: "When you store something in a dry place, it will not be damaged for a long time." And the temperature also needs to be controlled. If it is too high, it may cause chemical changes, resulting in damage to its structure. Therefore, you should find a library with a suitable temperature to store this thing.
Second, during transportation, beware of vibration and collision. This substance may decompose due to strong vibration, just like the ancients said "jade does not cut, it does not become a tool; things do not vibrate, and it exists". The packaging must be tight to cushion the impact of external forces.
Furthermore, because of its chemical activity, it cannot be co-stored and transported with oxidizing and reducing substances. "Water and fire are incompatible, and sexual antibodies are also separated". If mixed with it, it may cause violent reactions and endanger safety.
In addition, whether it is stored or transported, it is necessary to make a good label. Its name, characteristics and precautions are clearly stated so that relevant personnel can see it at a glance to avoid the risk of improper operation. In this way, 1H-pyrrole-3-carboxylic acid, 2,5-dimethyl-ethyl ester can be safely stored and transported.
