The method of preparing pyridine-3-hydrazin- hydrochloride (1:2), although the preparation of this specific substance is not detailed in the past books, it can be deduced according to the relevant chemical principles and the method of preparing analogs.
To prepare this substance, pyridine-3-hydrazine can be used as the starting material. This pyridine-3-hydrazine can be obtained from pyridine-3-carboxylic acid through a multi-step reaction. Pyridine-3-carboxylic acid is first converted into its acid chloride, and thionyl chloride is often reacted with it. After the acid chloride is formed, it is reacted with hydrazine to obtain pyridine-3-hydrazine.
After obtaining pyridine-3-hydrazine, pyridine-3-hydrazinyl-hydrochloride is prepared (1:2). In a suitable solvent, such as an alcohol solvent, pyridine-3-hydrazine is slowly reacted with hydrogen chloride gas or hydrochloric acid in a ratio of 1:2. Pay attention to the temperature during the reaction, and do not exceed it to prevent side reactions from occurring. In this process, the nitrogen atom of pyridine-3-hydrazine is combined with hydrogen chloride to form the corresponding hydrochloride salt. After the reaction, the product can be precipitated by evaporation of solvent, cooling and crystallization, etc., and then filtered, washed and dried to obtain pure pyridine-3-hydrazine-hydrochloride (1:2).
There may be other methods, such as using a compound containing pyridine-3-hydrazine structure as raw material and introducing hydrochloride through a specific chemical reaction. However, no matter what method, fine operation is required, and attention is paid to the control of reaction conditions to obtain the ideal product.

When using pyridine, 3-hydrazinyl -, hydrochloride (1:2), pay attention to everything. This material is chemically active, and it can cause discomfort by touching or inhaling its dust. There is a risk of irritation to the skin, eyes, and respiratory tract. Therefore, when handling, it is necessary to wear protective equipment, such as gloves, goggles, masks, etc., to prevent direct contact and inhalation.
Furthermore, its storage must also be cautious. It should be placed in a cool, dry and well-ventilated place, away from fire and heat sources, so as not to cause danger. Because it is easy to react with oxidants and other substances, it should not be stored and transported together with the like to prevent unexpected changes.
During use, strictly follow the procedures. Measure the required amount accurately, do not waste it by excessive use, and prevent excess from causing pollution. Dispose of the residue properly after use, and do not discard it at will to avoid polluting the environment. At the same time, the experimental site should be equipped with corresponding emergency treatment equipment. If there is accidental contact or accidental ingestion, it can be rescued in time. In this way, the use of pyridine, 3-hydrazine-hydrochloride (1:2) is safe and secure.
