There are three methods for synthesizing 2-chloro-4-hydroxymethylpyridine.
First, 4-methylpyridine is used as the starting material. The 4-methylpyridine is first chlorinated in a suitable solvent with a suitable chlorination agent, such as chlorine gas or N-chlorosuccinimide (NCS), in the presence of light or an initiator, so that the α-position of the methyl group is introduced into the chlorine atom to obtain 2-chloro-4-chloromethylpyridine. Subsequently, the product is reacted with nucleophiles, such as aqueous sodium hydroxide solution, at a suitable temperature, the chloromethyl group undergoes nucleophilic substitution, and the hydroxyl group replaces the chlorine atom to obtain 2-chloro-4-hydroxymethylpyridine. This route step is relatively simple, but the selectivity of the chlorination reaction needs to be carefully regulated to prevent the formation of polychlorinated by-products.
Second, start from 2-chloropyridine. The hydroxymethylation of 2-chloropyridine with formaldehyde and a suitable catalyst, such as Lewis acid, is carried out under specific reaction conditions. The carbonyl group of formaldehyde is activated by the catalyst, and electrophilic substitution occurs with the 4-position of 2-chloropyridine to introduce hydroxymethyl groups, and then the target product is obtained. The key to this method lies in the selection of catalysts and the optimization of reaction conditions to improve the yield and selectivity of the reaction.
Third, pyridine is used as the raw material. Pyridine is first chlorinated to introduce chlorine atoms at the 2-position, and then a suitable reagent, such as paraformaldehyde and zinc chloride, is used for hydroxymethylation, and hydroxymethyl is introduced at the 4-position. The raw material of this route is easy to obtain, but there are many reaction steps, and the reaction conditions of each step need to be strictly controlled to ensure the purity and yield of the final product. Each method has its own advantages and disadvantages, and the actual synthesis needs to be based on specific needs and conditions.

2-Chloro-4-hydroxymethylpyridine is a kind of organic compound. Its physical properties have several characteristics.
Looking at its properties, at room temperature, 2-chloro-4-hydroxymethylpyridine is mostly white to white solid powder, which is easy to store and handle, and the stability is guaranteed to a certain extent.
When it comes to melting point, its melting point range is roughly between [X] ° C and [X] ° C.

In summary, the physical properties of 2-chloro-4-hydroxymethylpyridine, such as its properties, melting point, solubility, density, etc., are of indispensable significance for its research, synthesis and application in the field of organic chemistry. Chemists can better manipulate the relevant chemical reactions and achieve the desired results by gaining a deep understanding and accurate grasp of these properties.

2-Chloro-4-hydroxymethylpyridine, the price of this product in the market is difficult to determine. The price of this product is influenced by various factors, just like the situation changes and is elusive.
First, it is related to output. If the output of this product is abundant and the market is abundant, its price may become more affordable, like a river following the trend, it will naturally be smooth. If the output is thin and the supply is in short supply, the price will rise. If the product is rare, the price will be high.
Second, the price of raw materials is also a major factor. If the raw materials are cheap, the cost of making this product will decrease, and the price in the market may be slightly lower; if the raw materials are expensive, the cost will increase, and the price will increase.
Third, the demand of the city will also determine the price. If the industry has a strong demand for this product, and there are many people who want it, the price will increase, just like everyone competing for treasure, and the price will rise; if the demand is weak, the market is deserted, and the price may decline, it seems that no one cares about the product, and the price is difficult to maintain.
Fourth, the quality of the craftsmanship also has an impact. Exquisite craftsmanship can reduce costs, improve product quality, and have competitive benefits; if the craftsmanship is crude, the cost is high and the quality is poor, the price will not be advantageous.
Looking at the past "Tiangong Kaiwu", the price of all things is affected by supply and demand, raw materials, processes, etc., similar to the price of 2-chloro-4-hydroxymethylpyridine. Although it is difficult to know the specific price in the current market, based on these factors, we can also get the clues of its price changes, which is necessary for market operators and buyers.

2-Chloro-4-hydroxymethylpyridine is one of the organic compounds. When storing and transporting, many matters need careful attention.
The first choice of environment. It should be stored in a cool, dry and well-ventilated place. If it is in a high temperature environment, or causes the compound to decompose, it will damage its quality; and if it is humid, it is easy to cause it to be damp and deteriorated, so a dry and ventilated environment is essential.
The second time and the strict packaging. It must be packed in a well-sealed container to prevent contact with air, moisture, etc. This compound may react chemically when exposed to air or moisture, which affects its chemical properties and purity. During transportation, the packaging should also be stable, capable of resisting vibration and collision, and avoiding material leakage caused by package damage.
Furthermore, the need for isolation. Do not mix with oxidants, acids, alkalis and other substances. Because of its active chemical nature, contact with the above substances, or trigger violent chemical reactions, causing fire, explosion and other dangers.
In addition, identification is indispensable. Storage containers and transportation vehicles should be clearly marked with their names, properties, danger warnings and other information. This is convenient for relevant personnel to identify and take appropriate protection and emergency measures.
During transportation, pay attention to the control of temperature and humidity. Some transportation vehicles should be equipped with temperature and humidity adjustment devices to ensure that the transportation environment is suitable. At the same time, transportation personnel should also be familiar with the characteristics of this compound and emergency treatment methods. In case of emergencies, they can respond quickly and minimize the harm. In this way, 2-chloro-4-hydroxymethylpyridine is safe during storage and transportation.
