From the perspective of physical properties, it is usually a colorless to light yellow liquid or solid, but the exact properties often vary according to its purity and environmental conditions. Its melting point is also a key physical property. The melting point may vary due to factors such as impurities, and the boiling point reflects the temperature at which it changes from liquid to gas under a specific pressure. In general, the boiling point can help to separate it from others in separation operations such as distillation.
As for chemical properties, the presence of pyrrole rings in this compound gives it special reactivity. Pyrrole rings are rich in electrons, so they are prone to electrophilic substitution reactions, such as halogenation, nitration, sulfonation, etc. Under appropriate conditions, groups such as halogen atoms and nitro groups can replace hydrogen atoms on pyrrole rings.
In addition, its ester groups also have typical chemical activity. Hydrolysis reactions can occur. Under acidic or basic conditions, ester groups are broken to form corresponding acids and alcohols, respectively. When hydrolyzed under basic conditions, 5-methyl-1H-pyrrole-2-carboxylic acid salts and ethanol are formed; when hydrolyzed under acidic conditions, 5-methyl-1H-pyrrole-2-carboxylic acid and ethanol are obtained. In addition, ester groups can also participate in reactions such as transesterification, exchanging alkoxy groups with different alcohols under the action of catalysts, thereby synthesizing new ester compounds.
Its methyl groups are also not inactive. Under appropriate reagents and conditions, hydrogen on the methyl group can be replaced or participate in some condensation reactions, thereby constructing more complex organic structures. Due to its many chemical properties, this compound occupies an important position in the field of organic synthesis and can provide key intermediates for the preparation of various compounds with biological and pharmaceutical activities.

The synthesis method of 5-methyl-1H-pyrrole-2-carboxylic acid ethyl ester has been known for a long time. There are many methods, so I will describe them now.
First, using 5-methyl-1H-pyrrole-2-carboxylic acid as the starting material, it is placed in a reactor with ethanol under the catalysis of concentrated sulfuric acid, and heated and refluxed. This process is like a universe in a kettle, with concentrated sulfuric acid as the medium to promote the esterification reaction between the two. However, concentrated sulfuric acid is highly corrosive, and it must be carefully added during operation to prevent accidents. After the reaction, the target product can be obtained through various steps such as neutralization, extraction, and distillation.
Second, 5-methylpyrrole and diethyl oxalate can also be used as raw materials. First, 5-methylpyrrole is mixed with strong bases such as sodium hydride to deprotonate the pyrrole nitrogen atom, as if activating its activity. Then diethyl oxalate is added to undergo a nucleophilic substitution reaction. This reaction is like a delicate chemical reaction dance, and the reactants interact in an orderly manner according to chemical laws. After the reaction is completed, 5-methyl-1H-pyrrole-2-carboxylic acid ethyl ester can be obtained after acidification and separation.
Third, there is a method that starts with a suitable halogenated hydrocarbon and 2-cyano-5-methyl pyrrole. The coupling reaction between halogenated hydrocarbons and 2-cyano-5-methyl pyrrole occurs under the action of metal catalysts such as palladium catalysts, which is like building a chemical bridge. Subsequent treatments such as hydrolysis and esterification of cyanyl groups can also obtain this product. This method requires specific metal catalysts, and the cost may increase. However, its selectivity is good, and it can be synthesized as a way.
All kinds of synthesis methods have advantages and disadvantages. In practical applications, the purpose of synthesis can be achieved only when careful decisions are made based on factors such as the availability of raw materials, cost considerations, and product purity requirements.

5-Methyl-1H-pyrrole-2-carboxylic acid ethyl ester, this is an organic compound. During storage and transportation, there are many things to pay attention to.
Let's talk about storage first. This compound should be placed in a cool, dry and well-ventilated place. Because it is afraid of moisture, if the environment is humid, or causes reactions such as hydrolysis, it will damage its quality. The storage temperature should be controlled within a moderate range, and it must not be too high, otherwise it may cause heat to decompose and cause it to deteriorate. And it should be kept away from fire and heat sources, because it has certain flammability, in case of open flame, hot topic or dangerous. It also needs to be stored separately from oxidants, acids, bases, etc., because of contact or chemical reaction with them.
As for transportation, also be cautious. The packaging must be tight to ensure that there is no risk of leakage. During transportation, it is necessary to protect against exposure to the sun, rain, and high temperature. When handling, it should be lightly loaded and unloaded, and should not be operated brutally to avoid package damage. Transportation vehicles should be equipped with corresponding fire equipment to deal with emergencies. And transportation should be carried on the specified route, and do not stop in densely populated areas or open flames. In this way, the safety and quality of 5-methyl-1H-pyrrole-2-carboxylate during storage and transportation can be ensured.

5-Methyl-1H-pyrrole-2-carboxylic acid ethyl ester, this product is in the market, its price varies from time to time, and also varies according to quality, quantity and origin. In the past, the price of various chemical products was often determined by many parties. If in an ordinary market, the quantity of this product is small and the quality is average, the price per gram may be in the tens of dollars. However, if you want its quality and quantity, the price is different.
