3-Bromo-2-methylpyridine is also an organic compound, and there are many ways to synthesize it. Here are some examples.
One method can be started with 2-methylpyridine. First, 2-methylpyridine is reacted with appropriate brominating reagents, such as bromine (Br ³), under suitable reaction conditions. Usually a catalyst is required, such as iron powder (Fe) or iron tribromide (FeBr ³). This catalyst can promote the electrophilic substitution reaction between bromine and 2-methylpyridine. At the time of the reaction, due to the electronic effect of the nitrogen atom on the pyridine ring, the bromine atom tends to be substituted at the 3-position of 2-methylpyridine, resulting in 3-Bromo-2-methylpyridine.
There are also those who use 2-methyl-3-hydroxypyridine as a raw material. First, 2-methyl-3-hydroxypyridine is reacted with a suitable halogenating agent, such as phosphorus tribromide. Phosphorus tribromide can replace the hydroxyl group with a bromine atom. After this step, the target product 3-Bromo-2-methylpyridine can also be obtained.
Furthermore, the method of metal-organic chemistry can be used. Using 2-methyl pyridine as the starting material, it first interacts with a strong base such as butyl lithium (n-BuLi) to lithium at a specific position on the pyridine ring to generate the corresponding lithium reagent. Then, it reacts with brominated reagents, such as copper bromide (CuBr) or brominated alkanes, and through metal transfer and substitution process, the synthesis of 3-Bromo-2-methylpyridine can also be achieved.
In addition, there are still other methods, and the way of synthesis often depends on the careful design and experimental exploration of chemists, depending on the availability of raw materials, the difficulty of reaction, and the high or low yield.

3-Bromo-2-methylpyridine is also an organic compound. During storage and transportation, many matters need to be taken care of.
First word storage. This compound should be placed in a cool, dry and well-ventilated place. Cover it or be sensitive to heat and humidity, warm and humid environment, may cause its chemical properties to change. For example, in case of moisture or hydrolysis reaction, its purity is damaged. And it must be kept away from fire and heat sources. Because organic materials are flammable, 3-bromo-2-methylpyridine may also be the same. In case of open flame or hot topic, there is a risk of combustion and explosion. Furthermore, it should be stored separately from oxidizing agents, acids, alkalis, etc., to cover their chemical activity. When encountering such substances, it is easy to cause chemical reactions, damage their quality, or even be dangerous. The storage place should also be equipped with appropriate equipment for containing leaks to prevent accidents.
Times and transportation. Before transportation, make sure that the container is well sealed and free from leakage. During transportation, the selected vehicle must be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment. During driving, drivers should drive slowly to avoid bumps and vibrations, so as to avoid leakage caused by damage to the container. At the same time, they should also drive according to the prescribed route to avoid densely populated areas and residential areas. When loading and unloading, the operator must be light and light, and it is strictly forbidden to drop, heavy pressure, and prevent packaging damage.
All of these are for the storage and transportation of 3-bromo-2-methyl pyridine. A little carelessness can cause disasters and endanger the safety of personnel and the environment.

3-Bromo-2-methylpyridine is also an organic compound. Its impact on the environment and human health is quite important to the world.
