The common synthesis methods of fugmethyl-5-bromo-2-pyridinecarboxylic acid are covered by the following numbers.
First, 2-pyridinecarboxylic acid is used as the starting material. First, it is brominated in a suitable solvent with a brominating agent, such as bromine (\ (Br_ {2}\)), and catalyzed by a catalyst, such as iron powder or iron tribromide. This reaction needs to be controlled at a suitable temperature range. Usually under the condition of heating and refluxing, the bromine atom selectively replaces the hydrogen atom at the 5-position on the pyridine ring to generate 5-bromo-2-pyridinecarboxylic acid. Subsequently, the obtained product is esterified with methanol in the presence of a catalyst such as concentrated sulfuric acid under heating conditions to obtain methyl-5-bromo-2-pyridinecarboxylic acid.
Second, 5-bromopyridine can be obtained. First, 5-bromopyridine is mildly oxidized, such as a suitable oxidant, such as a dilute solution of potassium permanganate or potassium dichromate, and under suitable reaction conditions, the methyl on the pyridine ring is oxidized to carboxyl groups to obtain 5-bromopyridine carboxylic acid. Then, according to the above esterification method, it reacts with methanol to form the target product.
Third, there are also those who use 2-methyl-5-bromopyridine as raw material. First, a suitable oxidation system, such as Jones reagent or Dess-Martin reagent, is used to oxidize methyl to carboxyl groups to obtain 5-bromo-2-pyridinecarboxylic acid, and then esterified to obtain methyl-5-bromo-2-pyridinecarboxylic acid.
All synthesis methods have their own advantages and disadvantages. The choice of starting materials depends on its availability, cost and ease of reaction. The fine regulation of reaction conditions is also related to the yield and purity of the product.

Methyl 5-bromo-2-pyridinecarboxylic acid is an important compound in organic chemistry. Its storage conditions are very critical, which is related to the stability and quality of this compound.
This substance should be stored in a cool, dry and well-ventilated place. In a cool environment, it can avoid decomposition or deterioration caused by high temperature. High temperature often causes chemical reactions to accelerate, causing changes in the structure and properties of compounds. Dry place to prevent moisture decomposition. Because moisture easily interacts with compounds, or causes adverse reactions such as hydrolysis, its purity and activity are damaged. Well ventilated, it can avoid the accumulation of harmful gases, and keep the air in the storage environment fresh, which is conducive to safety.
Furthermore, keep away from fire and heat sources. Fire and heat sources can easily cause hazards such as combustion or explosion, because this material may be flammable or react with heat. At the same time, it needs to be stored separately from oxidants, acids, alkalis, etc., to avoid mixed storage. These substances meet with methyl-5-bromo-2-pyridinecarboxylic acid, or cause violent chemical reactions, resulting in accidents.
Storage containers also need to be carefully selected. Sealed containers should be used to ensure that they are not disturbed by the external environment. Containers made of glass or specific plastic materials are commonly used, depending on the characteristics of the compound. Glass containers are chemically stable and suitable in most cases; if the compound has the potential to react with glass, special plastic containers should be selected.
In short, methyl-5-bromo-2-pyridinecarboxylic acid is stored in a cool, dry and ventilated place, away from the source of fire heat, separate storage of different substances, and choose suitable containers, so as to ensure its quality and safety.
