The synthesis method of 3-bromo-4-hydroxypyridine has been known since ancient times. There are many methods and each has its own strengths. Today, I will describe them in detail.
One of them can be prepared from 4-hydroxypyridine as the starting material through bromination reaction. In the reaction system, add an appropriate amount of brominating reagents, such as bromine, N-bromosuccinimide (NBS), etc. When bromine is used as the brominating agent, attention should be paid to the control of the reaction conditions. The reaction temperature should be carefully regulated. If it is too high, side reactions will occur, and if it is too low, the reaction will be delayed. It is often carried out in suitable solvents, such as dichloromethane, carbon tetrachloride and other inert solvents, to facilitate the smooth progress of the reaction. And during the reaction process, stirring must be applied to allow the reactants to fully contact and improve the reaction efficiency.
Second, using the pyridine derivative as the substrate, the hydroxyl group is introduced at a specific position first, followed by the bromination step. For example, select an appropriate pyridine derivative and make the hydroxyl group accurately access the target position through a suitable hydroxylation reaction. Then, as in the above bromination method, use a suitable brominating agent to achieve the introduction of bromine atoms under appropriate reaction conditions, and finally obtain 3-bromo-4-hydroxypyridine.
Third, the reaction path catalyzed by transition metals. The compound containing pyridine structure is used as the starting material, and under the catalysis of transition metal catalysts such as palladium and copper, with corresponding ligands, it works synergistically with bromine sources and hydroxylating reagents. This path requires quite strict reaction conditions, and the type and dosage of catalysts, as well as the choice of ligands, have a profound impact on the reaction results. However, its advantage is that it has high selectivity, which can effectively reduce the occurrence of side reactions and improve the purity of the product.
All these synthesis methods need to be carefully selected according to actual needs, such as the availability of raw materials, cost considerations, and product purity requirements, in order to achieve the desired synthesis effect.

3-Bromo-4-hydroxypyridine is an important chemical substance in organic synthesis. When storing and transporting, many matters need to be paid more attention.
Let's talk about storage first. This substance must be stored in a dry and well-ventilated place. Because it is quite sensitive to moisture, if the environmental humidity is high, it is very likely to absorb moisture and cause quality damage. For example, if placed in a humid place, it is easily eroded by water vapor, which affects its chemical properties. Temperature is also crucial and should be maintained within a suitable range. Usually, it is appropriate to be at room temperature. Do not expose it to a high temperature environment, otherwise it may cause decomposition and other adverse conditions. And it needs to be kept away from fire sources and oxidants, because in case of open flame or strong oxidant, it may burn or even explode, just like dry wood in case of fire, it is very easy to ignite. At the same time, it should be placed out of the reach of children to prevent accidental contact and injury.
Besides, the packaging must be tight and reliable to ensure that there will be no leakage during transportation. The means of transportation should be clean and dry, and there should be no other chemicals that may react with it. Avoid violent vibration and collision during transportation to avoid damage to the packaging. The transporter also needs to be familiar with its characteristics and emergency treatment methods, so that in case of accidental situations such as leakage, it can be dealt with quickly and properly. In conclusion, when storing and transporting 3-bromo-4-hydroxypyridine, it is necessary to strictly control environmental conditions, packaging, and personnel operations to ensure its safety and quality.

The "3-Bromo-4-hydroxypyridine" you are inquiring about is a chemical substance that is often priced in the market according to its characteristics and uses. However, its market price is not static and is influenced by many factors.
The first to bear the brunt is the difficulty of production. If its preparation requires complicated processes, rare raw materials, or harsh reaction conditions, the cost will be high, and its price will also rise. For example, if the required raw materials are difficult to collect, or the synthesis steps require precision instruments and superb skills, this will increase the cost and the market price will be high.
Furthermore, the state of market supply and demand is also the key. If there is a strong demand for this product in the fields of medicine, chemical industry, etc., but the supply is limited, according to market regulations, the price will rise. On the contrary, if the supply exceeds the demand, the merchant may reduce the price for promotion.
The difference between the origin and the manufacturer also affects the price. In different places, the cost of producing this product is different due to the amount of resources and labor costs. And the technical level and production scale of each manufacturer are different, and the cost and pricing are also different. Large manufacturers may be able to produce at a lower cost due to scale effects, and the pricing may be more competitive.
In addition, the competitive situation of the market, changes in policies and regulations, and even transportation and storage conditions all affect its price. Where competition is intense, manufacturers may adjust prices in order to compete for shares. If there are new regulations on environmental protection, production qualifications, etc., the policy will also change the cost and cause price fluctuations. If special conditions are required for transportation and storage, the cost will increase and the price will also be implicated.
Therefore, if you want to know the exact market price of "3 - Bromo - 4 - hydroxypyridine", you can get a more accurate price by carefully observing the current market factors, or consulting professional chemical product trading platforms and merchants.
