5-Bromo-2-isopropoxypyridine

5-Bromo-2-isopropoxypyridine, this is an organic compound. In terms of physical properties, it is often solid at room temperature, with a specific melting point and boiling point, but the exact value depends on the specific experimental conditions. Its solubility usually shows good solubility in organic solvents such as dichloromethane, chloroform, and tetrahydrofuran, because there is a suitable interaction between these organic solvents and the molecules of the compound, which can make the molecules uniformly disperse. However, the solubility in water is poor, because water is a polar solvent, it is quite different from the structure and polarity of the compound.
Chemical properties, bromine atoms are an important activity check point for this compound. It can participate in many nucleophilic substitution reactions. Under suitable nucleophilic reagents and reaction conditions, the nucleophilic test agent can attack the carbon atom attached to the bromine atom, causing the bromine ion to leave, and then generate new substitution products. For example, when reacted with sodium alcohol, new ether compounds can be formed. Although the existence of isopropoxy is relatively stable, it may also occur under strong acidic or strong basic conditions. Under acidic conditions, isopropoxy may undergo protonation, which in turn affects the electron cloud distribution and reactivity of the whole molecule; under alkaline conditions, reactions such as hydrolysis may occur. In addition, the pyridine ring imparts a certain alkalinity to the compound, because there are lone pairs of electrons on the nitrogen atom, which can accept protons. In some reaction systems, the compound can participate as a base, neutralize with acids, or catalyze certain reactions that require an alkaline environment.

The synthesis method of 5-bromo-2-isopropoxypyridine, although the ancient book "Tiangong Kaiwu" does not contain this substance, there are various paths to be found in organic synthesis today.
First, 2-hydroxypyridine is used as the starting material. Shilling 2-hydroxypyridine reacts with isopropylation reagents, such as isopropyl halide (isopropyl bromide or isopropyl chloride), in the presence of a base. The base can be selected from potassium carbonate, sodium carbonate, etc., in a suitable organic solvent, such as acetonitrile, N, N-dimethylformamide, heated and stirred, and after nucleophilic substitution, the hydroxyl group is replaced by isopropoxy to obtain 2-isopropoxypyridine. Then, bromine atoms are introduced into the 5-position of the pyridine ring with brominating reagents, such as liquid bromine and N-bromosuccinimide (NBS), under suitable conditions. If liquid bromine is used, it can be reacted in solvents such as glacial acetic acid under the catalysis of Lewis acid; if NBS is used, benzoyl peroxide is often used as the initiator to react in solvents such as carbon tetrachloride.
Second, 2-chloropyridine is used as the starting material. First, it undergoes a nucleophilic substitution reaction with isopropanol catalyzed by a base, such as potassium tert-butanol, etc. The solvent can be selected from tetrahydrofuran, etc., to obtain 2-isopropoxypyridine, and then 5-position bromine atoms are introduced according to the above bromination method.
Third, it can also be designed to be synthesized through the construction of pyridine rings. For example, with a suitable nitrogen-containing and carbonyl-containing compound, a pyridine ring is constructed through a multi-step reaction, and isopropoxy and bromine atoms are introduced at a suitable stage at the same time. For example, β-ketone esters and ammonia or amine compounds are condensed to form pyridine rings under suitable conditions, and then isopropoxy and bromine atoms are introduced through functional group transformation. These methods have their own advantages and disadvantages. According to the actual situation, consider the availability of raw materials, the difficulty of reaction conditions, and the high or low yield.

5 - Bromo - 2 - isopropoxypyridine is also an organic compound. Its market price changes capriciously and is influenced by many factors.
The price of raw materials, at the cost end, weighs heavily. If the price of starting materials required for the synthesis of this compound, such as specific pyridine derivatives, brominating reagents, isopropoxypyridine reagents, etc., fluctuates due to changes in origin, production, and market supply and demand, the price of 5 - Bromo - 2 - isopropoxypyridine also fluctuates. If the origin of raw materials suddenly changes, resulting in a sharp decrease in output, its price will rise, product costs will increase, and market prices will also rise.
The method of synthesis also affects the price. An efficient and economical process can reduce costs and give the product a price advantage in the market. For example, a new method has simple reaction steps, high yield, low energy consumption, can reduce production costs, and the price may be close to the people. On the contrary, the complicated and inefficient old method has high costs and it is difficult to reduce product prices.
The market supply and demand situation is a key factor. If the demand for it in the pharmaceutical, pesticide and other industries increases sharply at a certain time, but the supply is limited, the price will rise. If a new type of drug is developed, a large amount of this compound is required as an intermediate, and the demand exceeds the supply, and the price will rise. If the production capacity expands too fast and the supply exceeds the demand, the price will decline.
Furthermore, regulations and policies, transportation costs, storage conditions, etc., all have an impact on its price. With stricter regulations, production compliance costs increase, and prices may rise; long transportation distances, rising oil prices, high transportation costs, and prices are also affected; storage requires special conditions, costs increase, and prices change.
Looking at it all, in order to know the exact market price of 5 - Bromo - 2 - isopropoxypyridine, it is necessary to pay real-time attention to the raw material market, production process innovation, supply and demand dynamics, and related policies in order to grasp the trend of its price.

5-Bromo-2-isopropoxypyridine is one of the organic compounds. The most important thing for its storage is to avoid heat and open flames. Because of hot topics or in the event of open flames, this substance may cause the risk of combustion and endanger the surrounding.
