There are several common synthesis methods for 2-chloro-3-pyridyl methanol.
One is to use 2-chloro-3-pyridyl carboxylic acid as the starting material. This acid first reacts with lithium aluminum hydride in a suitable organic solvent at low temperature and in a nitrogen-protected atmosphere. Lithium aluminum hydride has strong reductive properties and can reduce carboxyl groups to hydroxymethyl groups to obtain 2-chloro-3-pyridyl methanol. After the reaction is completed, the product is separated and purified through post-treatment steps such as hydrolysis. The raw materials of this method are relatively easy to obtain, but lithium aluminum hydride is active in nature. The reaction needs to be handled carefully, and the post-treatment process needs to be meticulous to prevent product loss or the introduction of impurities.
The second is to use 2-chloro-3-pyridine formaldehyde as the starting material. In a suitable reaction system, the reduction reaction is carried out in an alcohol solvent with sodium borohydride or potassium borohydride as the reducing agent. Such reducing agents are relatively mild and the reaction conditions are easy to control. Borohydride provides hydrogen negative ions and attacks the carbonyl carbon of the aldehyde group. After protonation, 2-chloro-3-pyridine methanol is generated. After the reaction, pure products can be obtained by conventional separation methods such as distillation, extraction, column chromatography, etc. This route is relatively simple to operate and does not require harsh reaction equipment. It is suitable for small and medium-scale synthesis.
Others use 2-chloropyridine as raw material. First, 2-chloropyridine is reacted with paraformaldehyde, zinc chloride, etc. under specific conditions to introduce hydroxymethyl groups. This reaction involves an electrophilic substitution mechanism, and the reaction temperature, time and proportion of reactants need to be precisely controlled. After the reaction is completed, the target product 2-chloro-3-pyridine methanol can be obtained after multiple steps of separation and purification. This method is a little complicated, but the raw materials come from a wide range. If the reaction conditions are optimized, efficient synthesis is expected.

2-Chloro-3-pyridyl methanol, its market value can be determined by a certain amount. The price of this product is affected by many factors, such as product quality, supply and demand, quantity, place of transaction, and market volatility.
If the quality of the product is high, the high quality will be higher because of its large cost and high cost. The market supply and demand, if more supply is less, the price is often high; conversely, the supply is different from the demand, or there is a drop in the price. The quantity also has an impact, a large amount of money, or because of the benefit of the model, the price is reduced; a small amount of money, and the price of the product is high.
The place of transaction is different, and the price is also low. In places where the chemical industry is concentrated and raw materials are easy to use, the cost is low, and the cost is low or more. In places where the cost is increased, the cost is low or slightly higher.
And the market is not inhabited, the quality of raw materials, the innovation of biotechnology, and the policy and law can all make the price of 2-chloro-3-pyridyl methanol fluctuate. Therefore, in order to know the quality of its market, it is necessary to follow the situation and sell chemical raw materials to suppliers.
