3 - Bromopyridine - 2,4 - diol is an important organic compound, and there are many methods for its synthesis. The common method is to use pyridine derivatives as the starting material.
First, pyridine containing suitable substituents can be introduced into bromine atoms through halogenation reaction, and then hydroxylation reaction can be used to introduce hydroxyl groups at specific positions. For example, pyridine is brominated first, the reaction conditions are controlled, and the bromine atoms are precisely replaced to the target position, and then the hydroxylation is achieved by using suitable reagents and conditions to obtain 3 - Bromopyridine - 2,4 - diol. In this process, the halogenation reaction needs to select a suitable halogenated reagent and reaction environment to ensure the accuracy of the substitution position; the hydroxylation step needs to consider factors such as reagent activity, reaction temperature, time, etc., to ensure the successful introduction of hydroxyl groups and the purity of the product.
Second, the strategy of gradually constructing pyridine rings can also be used. Small molecules containing bromine and potential hydroxyl functional groups are synthesized first, and then pyridine rings are constructed by cyclization. In this approach, the synthesis of small molecules requires careful design of reaction routes to ensure the relative position and activity of functional groups; during cyclization, the reaction conditions should be regulated to promote smooth cyclization of molecules, while avoiding side reactions, in order to achieve higher yield and purity.

3 - Bromopyridine - 2,4 - diol is a chemical substance that requires careful attention in many aspects when storing and transporting.
Store first. This substance is quite sensitive to environmental conditions and is first dry. Humid gas can easily cause it to deteriorate, so it should be placed in a dry place, away from water sources, and the surrounding humidity should be controlled at a low level. Temperature is also critical, not too high or too low, usually at room temperature. Due to extreme temperatures or chemical reactions, it will affect its chemical properties. Furthermore, it is necessary to prevent it from coming into contact with other chemicals, especially those with strong oxidizing or reducing properties, so as not to cause dangerous reactions. The storage place should be well ventilated to avoid the accumulation of harmful gases.
As for transportation, the packaging must be tight. Appropriate packaging materials should be selected to ensure that they are not affected by vibrations and collisions during transportation to prevent leakage. Transportation vehicles should be clean and free of other substances that may react with them. Transport personnel should also be familiar with their characteristics and emergency treatment methods. In the event of an accident, they can respond quickly and correctly. Transportation route planning should also pay attention to avoid densely populated areas and environmentally sensitive places to prevent leakage from causing serious harm to people and the environment. In this way, the safety and stability of 3-Bromopyridine-2,4-diol during storage and transportation should be guaranteed.

3 - Bromopyridine - 2,4 - diol is a chemical substance whose market price varies due to a variety of factors. The complexity of the synthesis or extraction process of this substance, the amount of market demand for it, and the size of the production scale all affect its price.
If the synthesis process is complicated, rare or expensive raw materials are required, or the operating conditions are harsh, the production cost will rise, and the market price will also rise. Furthermore, if the market demand for this substance is strong and the supply is limited, the state of supply will push up the price; conversely, if the demand is low and the supply is sufficient, the price may decline.
However, there is no conclusive uniform pricing in the market today. Based on past transactions and market conditions, the price range is relatively wide. For transactions with average purity and small batches, the price per gram may range from tens of yuan to hundreds of yuan; if the purity is extremely high, or the purchase volume is quite large, the unit price may be significantly reduced due to the scale effect, from a few yuan to a few tens of yuan per gram. However, this is only a rough estimate. The real price needs to be consulted with chemical raw material suppliers in detail, or the recent transaction data on the relevant chemical product trading platform can be obtained. Price information close to market conditions can be obtained.
