To prepare 5-methylpyrrole-2-carboxylic acid, the method is as follows:
First, it can be obtained from the corresponding halogenate through substitution reaction. First, take a suitable halogenated hydrocarbon, and under suitable reaction conditions, replace it with a carboxyl-containing nucleophilic reagent. For example, looking for a halogenated methyl pyrrole derivative, placing it in an alkaline environment, co-heating with a carboxylate, leaving the halogen atom, and substituting the carboxyl group for its position. Through this step, the precursor of the target product can be obtained, and then after appropriate acidification treatment, 5-methylpyrrole-2-carboxylic acid can be obtained.
Second, it can be started from the construction of pyrrole rings. A pyrrole ring is formed from a raw material containing methyl and carboxyl groups through a multi-step reaction. If a suitable active compound containing methyl and carboxyl groups is selected, in the presence of a specific catalyst, a series of reactions such as condensation and cyclization can be used to construct a pyrrole ring structure. For example, a methyl-containing β-dicarbonyl compound and a carboxyl-containing amine compound are used under acid catalysis to form an enamide intermediate first, and then an intramolecular cyclization is used to construct a pyrrole ring, and finally 5-methylpyrrole-2-carboxylic acid is formed.
Third, it can be prepared by carboxylation of 5-methylpyrrole. 5-Methylpyrrole is placed in a suitable reaction system, and a reagent that can introduce carboxyl groups is added, such as a system composed of carbon dioxide and a suitable metal catalyst. Under a certain temperature and pressure, carbon dioxide reacts with 5-methylpyrrole as a carboxyl group source, and the carboxyl group is introduced at the second position of the pyrrole ring to obtain 5-methylpyrrole-2-carboxylic acid.
All methods have their own advantages and disadvantages. In actual preparation, when the availability of raw materials, the difficulty of reaction conditions, the yield and other factors weigh and choose.

2-Boric acid has many key precautions to pay attention to during storage and transportation.
In terms of storage, first, a dry, cool and well-ventilated place should be selected. Because boric acid has a certain degree of hygroscopicity, if the storage environment is humid, it is easy to cause it to get wet and agglomerate, thus affecting the quality and performance. Therefore, in the warehouse, the humidity should be strictly controlled within a specific range, and must not be too high. Second, it should be stored separately from oxidants, alkalis and other substances. The chemical properties of boric acid are relatively active, contact with oxidants, or cause violent chemical reactions, and even the risk of combustion and explosion; when coexisted with alkali substances, it is easy to neutralize and cause its deterioration and failure. Third, the storage place must be equipped with suitable containment and leakage materials. In the event of leakage, it can be collected in time and effectively to prevent its spread, avoid pollution to the environment, and facilitate subsequent proper treatment.
In terms of transportation, the first priority is that the packaging should be solid and firm. Appropriate packaging materials must be used to ensure that boric acid does not leak during the transportation turbulence. Warning labels should be clearly marked on the outside of the package, such as "moisture-proof" "avoid mixing with oxidants and alkalis" to remind transporters. Secondly, the transportation process should be protected from exposure to the sun and rain. Prolonged exposure to the sun can raise the temperature of boric acid, or cause chemical changes; rain exposure directly causes it to get damp, which seriously affects the quality. Furthermore, the transportation vehicle should also be kept clean and dry, and other substances that may react with boric acid should not be transported to prevent mixing phenomenon to ensure transportation safety. In this way, the purpose of safe storage and transportation of boric acid can be achieved to ensure that it can maintain good performance and quality in all aspects.
