There are many ways to synthesize 4 '-bromo-2,2': 6 ', 2' -tripyridine. First, it can be prepared by halogenation reaction. First, take 2,2 ': 6', 2 '-tripyridine as raw material, and under suitable reaction conditions, such as in an organic solvent, use a specific halogenating reagent, such as N-bromosuccinimide (NBS), to participate in the reaction. In an inert gas-protected atmosphere, slowly warm to a suitable temperature and maintain it for a period of time. During this process, the halogenating reagent will react with 2,2': 6 ', 2' -tripyridine at a specific position, resulting in 4 '-bromo-2,2': 6 ', 2' -tripyridine. < Br >
Second, it can be synthesized by coupling reaction between bromoaryl compounds and pyridine derivatives. For example, bromoaryl halides and 2-pyridyl boronic acid derivatives are reacted in an alkaline environment and a specific organic solvent system in the presence of transition metal catalysts such as palladium catalysts. By adjusting the reaction temperature, time and the proportion of each reactant, the two are coupled to construct the molecular structure of 4 '-bromo-2,2': 6 ', 2' -tripyridine.
Furthermore, a stepwise synthesis strategy can also be used. First synthesize the intermediate with some structural fragments, and then gradually introduce the required functional groups and structural units through multi-step reactions, and finally achieve the synthesis of 4 '-bromo-2,2': 6 ', 2' -tripyridine. Each step of the reaction requires fine control of the reaction conditions to ensure the smooth progress of the reaction and improve the yield and purity of the product.

4 '-Bromo-2,2': 6 ', 2' -tripyridine is an organic compound, and the following matters should be paid attention to when storing.
First, it is essential to avoid moisture. This compound is susceptible to moisture, causing its quality to deteriorate, or even triggering a chemical reaction. Therefore, it needs to be stored in a dry place, and desiccants, such as silica gel, can be used to keep the environment dry and prevent it from being damaged by moisture.
Second, temperature control is also indispensable. It should be placed in a cool environment, protected from high temperature and direct sunlight. High temperature will destroy the stability of the compound and accelerate decomposition or deterioration. Generally speaking, the storage temperature is 2-8 ° C. If the requirements are not harsh, room temperature (15-25 ° C) and a cool place can also be used, but it is necessary to avoid large temperature fluctuations.
Third, anti-oxidation cannot be ignored. The compound may have a certain degree of reductivity and is easy to react with oxygen in the air. Sealed storage can be adopted. Fill the container with an inert gas such as nitrogen to drain the air to reduce the risk of oxidation.
Fourth, store in a suitable container. Glass or specific plastic containers should be used to ensure that the container is well sealed. Glass containers are chemically stable and do not react with compounds; plastic containers should be selected with good chemical stability to prevent interaction.
Fifth, classified storage. Because it is a chemical, it needs to be separated from other chemicals, especially oxidizing, acidic, and alkaline substances, to avoid dangerous reactions. Strictly follow the chemical storage specifications, place it in an exclusive area, clearly marked, easy to access and manage, and ensure storage safety. In this way, 4 '-bromo-2,2': 6 ', 2' -tripyridine can ensure stable quality during storage for subsequent use.

Today I have a question, what is the price of 4-bromo-2,2 ': 6', 2 '-tripyridine in the market. This is a chemical substance, and if you want to know its price, you need to look at all the reasons.
First, look at its purity. If the purity is extremely high, almost perfect, and there is no impurity interference, such high-quality products will be very expensive. Due to the difficulty of preparation and the complexity of the process, it must be purified layer by layer by exquisite method. If you want the purity to be 99.99, the price is higher than that of ordinary purity, or twice or even several times.
Second, look at the source of production. Manufactured by a well-known factory, its equipment is well-equipped, the control is strict, the quality of the products produced is excellent, and the price will be high. And the products produced by a small factory without a name, although they can also be used, the quality may vary, and the price should be slightly lower.
Third, observe the supply and demand of the market. If there are many people who want it, but there are few suppliers, if there is a lot of scientific research needs, or the industry is eager for this thing, the price will rise. On the contrary, if this thing is piled up in the market, and there is little demand, the price may drop.
Fourth, it is related to the volume of transactions. If you block trade and buy a lot at one time, the merchant may give a discount to promote the sale, and the total price may be reduced. If you only buy a small amount for research purposes, the merchant may have a higher unit price due to cost considerations.
However, I have not personally involved in the market of chemical transactions, so it is difficult to determine the price. If you want to know the exact price, you can consult the merchant of chemical raw materials, or visit the platform of relevant transactions, so that you can get the recent confirmed price.
