The method of preparing 2-bromo-4-pyridinecarboxylic acid has been used in various ways throughout the ages. First, it can be started from 4-pyridinecarboxylic acid and obtained by bromination reaction. In this reaction, appropriate brominating reagents, such as bromine ($Br_2 $), are often used under specific reaction conditions. Generally speaking, suitable solvents, such as inert organic solvents such as dichloromethane, are required to facilitate the smooth occurrence of the reaction. At the same time, in order to make the reaction proceed smoothly, a catalyst, such as iron powder or iron tribromide, may be added. This catalyst can promote the polarization of bromine molecules, and it is easier to undergo electrophilic substitution reaction with the pyridine ring, and then introduce bromine atoms at the 2-position of the pyridine ring to obtain the target product 2-bromo-4-pyridinecarboxylic acid.
Second, it can also start from 2-bromo-pyridine. First, the carboxyl group is introduced at the 4-position of the pyridine ring by a suitable method. For example, by the Grignard reagent method. 2-bromo-pyridine is made into Grignard reagent, that is, it reacts with magnesium chips in anhydrous ether or tetrahydrofuran and other solvents to generate the corresponding Grignard reagent. Then, the Grignard reagent is reacted with carbon dioxide, and the carboxyl group can be successfully introduced at the 4-position after subsequent hydrolysis treatment, and the final product is 2-bromo-4-pyridinecarboxylic acid.
Furthermore, using pyridine derivatives containing suitable substituents as raw materials, the target molecular structure is gradually constructed through multi-step reactions. For example, starting from a pyridine compound with functional groups that can be converted into bromine and carboxyl groups, the conversion of functional groups and the synthesis of the target product are gradually realized through a series of organic reactions such as substitution, oxidation, and reduction. Although this approach has many steps, it can better control the selectivity of the reaction and the purity of the product under certain circumstances.

2-Bromo-4-picolinecarboxylic acid is a chemical substance, and many things need to be paid attention to when storing.
The first to bear the brunt, this chemical substance must be stored in a cool, dry and well-ventilated place. Because it is sensitive to heat, high temperature can easily decompose or deteriorate, so it is necessary to keep away from heat sources, fire sources and direct sunlight.
