To prepare 2 - (chloromethyl) - 3,4 - dimethoxypyridine hydrochloride (1:1), you can follow the following method.
Take 3,4 - dimethoxypyridine as the starting material first, because the pyridine ring has certain basic and nucleophilic properties. Place it in a suitable reaction vessel and add an appropriate amount of organic solvent, such as dichloromethane, chloroform, etc., to create a homogeneous reaction environment, which is conducive to full contact of the reactants.
After that, slowly add chloromethylation reagents, such as chloromethyl ether or triformaldehyde and hydrogen chloride complex. This step requires careful control of the reaction temperature, usually maintained at a low temperature, such as 0 - 10 ° C, to prevent excessive side reactions. Due to the nucleophilic substitution reaction of the active site of the pyridine ring with the chloromethylating reagent under suitable conditions, the chloromethyl group will replace the hydrogen atom at a specific position on the pyridine ring to generate 2- (chloromethyl) -3,4-dimethoxy pyridine.
The reaction process should be monitored by thin layer chromatography (TLC). When the raw material point is basically eliminated and the product point is the main one, it indicates that the reaction has reached the expected degree. Subsequently, the reaction solution is treated, such as washing with dilute alkali solution, to remove the unreacted chloromethylating reagent and by-products, and then dried with anhydrous sodium sulfate to remove the water in the system.
Next, dry hydrogen chloride gas is introduced into the dried reaction solution. This operation needs to be carried out in a low temperature and dry environment, because the lone pair electrons of the nitrogen atom in 2- (chloromethyl) -3,4-dimethoxypyridine can combine with the hydrogen ion in hydrogen chloride to form the corresponding hydrochloride, which is to obtain 2- (chloromethyl) -3,4-dimethoxypyridine hydrochloride (1:1). Finally, the product is purified by means of filtration and recrystallization to obtain a high-purity target product. During the whole process, careful control of the reaction conditions and accurate operation of each step are the keys to successful preparation.

Guanfu 2 - (chloromethyl) -3,4 -dimethoxypyridine hydrochloride (1:1) The price of this product in the market is often difficult to determine. The fluctuation of its price depends on various factors.
The abundance of raw materials is the main reason. If raw materials such as chloromethyl and dimethoxypyridine are widely available and available, their price will be flat. On the contrary, if raw materials are scarce, the demand is too high, and the price will surge.
The difficulty of preparation also has an impact. If the synthesis method is cumbersome, requires exquisite craftsmanship, precious agents, or takes a long time, the cost will increase, and the price will also be high. However, if there is a new and clever way to simplify the process and reduce the cost, the price is expected to be lower.
The demand of the city also affects the price. In the fields of medicine and chemical industry, if the product needs to be used more and more, and the merchants compete to buy it, the price will rise. If it needs to be used less and less, the goods will be accumulated, and the price will be reduced.
Furthermore, changes in the world situation and regulations of government orders also affect the price. Trade policies and environmental protection regulations can cause changes in costs, and prices vary accordingly.
As for the actual price, it is difficult to determine. It is necessary to consult the chemical raw materials market in detail, visit the suppliers, compare their quotations, and observe the change of the situation before you can get a more accurate price. Or consult the senior in the chemical industry, you can also hear the approximate price and the reason for the change.

2-%28chloromethyl%29-3%2C4-dimethoxypyridine+hydrochloride+%281%3A1%29, it is a chemical substance. When storing and transporting, all precautions should not be ignored.
The first word of storage, this substance should be placed in a cool, dry and well-ventilated place. It covers its properties or has a poor pool due to changes in temperature and humidity. In a high temperature and humid place, it is easy to cause it to deteriorate. And it must be kept away from fires and heat sources to prevent fires. It should also be stored separately from oxidants, acids, alkalis, etc., and must not be mixed to prevent chemical reactions, damage its quality, or even risk.
