To prepare 6-chloro-3-pyridyl acetic acid, the following methods are often followed.
First, start with 6-chloronicotinic acid. First, 6-chloronicotinic acid is reacted with a reducing agent such as sodium borohydride and a catalyst in a suitable solvent for temperature control to reduce the carboxyl group to an alcohol hydroxyl group to obtain 6-chloronicotinol. Next, 6-chloronicotinol is treated with a halogenating agent such as sulfoxide chloride or phosphorus tribromide to convert the hydroxyl group into a halogen atom to generate 6-chloro-3-halomethylpyridine. Then, sodium cyanide or potassium cyanide is reacted with it to introduce a cyanyl group to obtain 6-chloro-3-cyanomethylpyridine. Finally, the cyanyl group is hydrolyzed under the catalysis of an acid or base to obtain 6-chloro-3-pyridyl acetic acid.
Second, 3-methyl-6-chloropyridine is used as a base. The methyl group is halogenated by a halogenating reagent such as N-bromosuccinimide (NBS) and an initiator under light or heating conditions to obtain 6-chloro-3-halomethylpyridine. The following steps are the same as the above-mentioned 6-chloro-3-halomethylpyridine, that is, the target product is obtained by cyanidation and hydrolysis.
Third, pyridine is used as the starting material. First, chlorination is carried out to introduce chlorine atoms into the pyridine ring at a suitable position, and then acetyl groups are introduced into the pyridine ring at a suitable check point under the action of catalysts. After a series of oxidation, substitution, hydrolysis and other reactions, it is gradually converted to obtain 6-chloro-3-pyridine acetic acid. However, this approach step is slightly complicated, and the reaction conditions of each step need to be carefully controlled.
All kinds of synthesis methods have their own advantages and disadvantages. When actually operating, we should carefully choose according to various factors such as the availability of raw materials, cost considerations, difficulty of reaction, and high or low yield.

The market price range of 6-chloro-3-pyridyl acetic acid is difficult to determine. Its price varies depending on many factors. This compound is widely used in chemical and pharmaceutical industries, but its price in the market is often affected by raw material costs, production processes, market supply and demand, etc.
In the past, the cost of raw materials was one of the major factors affecting its price. If the price of the basic raw materials required to prepare 6-chloro-3-pyridyl acetic acid fluctuates, the price of the finished product will also change. If the supply of raw materials is short, or the cost of preparing raw materials is changed, the price of 6-chloro-3-pyridyl acetic acid will increase.
The production process is also the key. Advanced and efficient processes can reduce production costs. If the process is complex and inefficient, and consumes a lot of manpower and material resources, the product price will be high.
Furthermore, the market supply and demand relationship plays a significant role. When the demand for this product in fields such as pharmaceutical research and development increases sharply, and the supply does not keep up in time, its price will rise; on the contrary, if the supply exceeds demand, the price will decline.
From this perspective, the market price of 6-chloro-3-pyridyl acetic acid is difficult to generalize. It fluctuates in different ranges, or ranges from hundreds to thousands of yuan per kilogram. It needs to be carefully investigated according to the current market conditions.

6-Chloro-3-pyridyl acetic acid, this is a chemical substance, and many things need to be paid attention to when storing and transporting.
Let's talk about storage first, and choose the first environment. When placed in a cool and dry place, avoid high temperature and humidity. Due to excessive temperature, or its chemical properties may change, and moisture can easily lead to deliquescence and damage its quality. In the warehouse, it must be well ventilated to ensure air circulation and prevent the accumulation of harmful gases.
Furthermore, it should be placed separately from different types of chemicals. Such as oxidants, reducing agents, acids, bases, etc., should not be coexisted in the same room. Due to its different chemical activities, it is easy to mix with chemical reactions, and even cause dangerous accidents, such as combustion and explosion.
Packaging is also key. It must be packed in a well-sealed container to prevent leakage. The packaging material should also be adapted to withstand its chemical properties and not react with it.
As for transportation, it is essential to clean and dry the means of transportation. Before loading the car, make sure that there are no sundries or water stains in the car, otherwise it may be contaminated.
During transportation, drive slowly to avoid bumps and sudden brakes. Violent vibration or damage to the package, causing leakage. And the transportation environment temperature should also be controlled, not too high or too low.
When loading and unloading, caution is required. Operators should wear suitable protective equipment, handle lightly, do not drop, heavy pressure, and keep the packaging intact.
Only by paying attention to the above during storage and transportation can the safety and quality of 6-chloro-3-pyridyl acetic acid be ensured.
