To prepare 3-alkynyl-2-furanyl-5- (trialkynyl methyl) pyridine, the following ancient methods can be used.
First, furan and alkynyl halide are used as the starting point, and the nucleophilic substitution reaction is carried out to obtain 2-halofuranyne intermediates. This step needs to be carried out in a suitable organic solvent under the catalysis of a base, such as potassium carbonate, and a solvent such as N, N-dimethylformamide (DMF). Temperature control reaction, so that the 2-position hydrogen of furan is replaced by alkynyl halogen.
Then, the resulting intermediate is reacted with trialkynyl pyridine derivatives. This reaction also needs to be carried out in a suitable solvent such as tetrahydrofuran (THF) under alkali catalysis. With the help of palladium-catalyzed coupling reaction, the two are connected. A palladium catalyst such as tetra (triphenylphosphine) palladium (0), and a ligand such as tri-tert-butyl phosphine are added to promote the reaction to obtain the target product.
Second, a skeleton containing furyl and pyridine can be prepared first. Furan-2-formaldehyde and a suitable pyridine derivative are used to construct the basic skeleton through condensation reaction. The reaction is carried out under acidic or basic conditions in an alcohol solvent such as ethanol.
Then, the resulting skeleton is introduced into the alkynyl group and trialkynyl methyl. With halogenated alkynes and trialkynyl methyl halides, under the catalysis of metal reagents, such as the Sonogashira reaction catalyzed by copper reagents, in alkaline environments, such as diethylamine solutions, the halogenated groups are replaced by alkynyl groups and trialkynyl methyl groups. The purpose of preparing the target product can also be achieved through this step.
When operating, it is necessary to pay attention to the precise control of the reaction conditions, such as temperature, reactant ratio, catalyst dosage, etc., which have a great impact on the yield and selectivity of the reaction. At the same time, the reaction solvent needs to be dried and pure to avoid impurities interfering with the reaction process. After each step of the reaction, the product should be properly separated and purified to ensure the smooth reaction of the next step.

Today there is 3-hydroxy-2-furyl-5- (trihydroxymethyl) pyridine, what is the market price?
Looking at this product, it is difficult to determine the market price. The fluctuation of its price is related to multiple ends.
First, it is related to the quality of this product. If the quality is pure and excellent, and there are few impurities, it can be used with all kinds of precision, the price will be very high. On the contrary, if the quality is not high and there are a little more impurities, it is only suitable for ordinary needs, and its price will be low.
Second, it is related to the trend of supply and demand. If there are many people in the world who need this 3-hydroxy-2-furyl-5- (trihydroxymethyl) pyridine, but there are few suppliers, the supply is in short supply, and its price must rise. If the supply exceeds the demand, the goods are in the market, and the price may drop.
Third, it is related to the production method and cost. If the production method is complicated, the materials required are rare and expensive, and the cost of manpower and material resources is quite high, the price will be high. If the production method is simple, the materials are easy and inexpensive, and the cost decreases and the price also decreases.
Fourth, it is related to the competition in the market. There are many households in the market that make this product, and they compete to sell it to attract customers, or reduce the price for profit. If the manufacturer is small and almost unique, the price can be determined by itself and often remains high.
In summary, in order to determine the market price of 3-hydroxyl-2-furyl-5- (trihydroxymethyl) pyridine, it is necessary to carefully consider its quality, supply and demand, cost and market competition before obtaining a more accurate price. However, it is difficult to say the price of its price without knowing the situation at present.

3-Hydroxy-2-furyl-5- (trihydroxymethyl) pyridine There are many things to pay attention to during storage and transportation.
First, when storing, be sure to choose a cool, dry and well-ventilated place. Because of its nature or will be significantly affected by humidity and temperature, if the environment is humid, it is easy to cause moisture and deterioration, so it should be ensured that the storage place is dry and wet. And the temperature should not be too high. Excessive temperature may cause its chemical reaction, causing the material properties to change and lose its original characteristics.
Second, the storage place should be away from fire and heat sources. This substance may be flammable to a certain extent. In case of open flames and hot topics, it is easy to cause the danger of combustion or even explosion, which endangers the safety of the surrounding area. Therefore, in the warehouse, fireworks are strictly prohibited, and all kinds of electrical equipment must also meet the standards of fire and explosion prevention.
Third, during transportation, it needs to be properly packaged. According to its chemical properties, suitable packaging materials should be selected to ensure that the packaging is tight to prevent leakage. Once leaked, it will not only cause material loss, but also cause pollution to the environment. If it comes into contact with the human body, it may also endanger personal health.
Fourth, transportation vehicles also need to meet specific requirements. The car should be clean and free of debris to avoid other substances from reacting with it. At the same time, the transportation qualifications of the vehicle should also be complete. Drivers and escorts need to be familiar with the characteristics of the substance and emergency treatment methods. If an accident occurs on the way, they can respond quickly and correctly to reduce the harm.
Fifth, during storage and transportation, detailed records should be made. The records cover information such as warehousing time, quantity, storage conditions, and transportation route. Such records are convenient for traceability and management. Second, when problems occur, they can provide an important basis for finding the cause and solving the problem.
