If you want to make n-hydroxy-4-pyridinecarboximidamid, there are many methods, which can be discussed according to the ancient method and the current method.
The ancient method, or take natural things, through complex refining, in order to obtain the required. First find the plants rich in related ingredients, pick their branches, leaves and rhizomes, wash and dry them, use water or alcohol as a solvent, soak them. After soaking, filter their liquid, remove their residues, and then use distillation, evaporation, etc., to concentrate the liquid. During the process, you need to carefully check the temperature and duration, and if there is a slight difference, it will fall short. However, the impurities obtained in this method are quite large, and if you want to obtain pure products, you need to purify them carefully.
The current method relies on the technique of chemical synthesis. First, 4-pyridinecarboxylic acid is used as the starting material, and it is first reacted with appropriate reagents to form its derivatives, and then hydroxylated to introduce hydroxyl groups. This process requires precise control of reaction conditions, such as temperature, pH, and the proportion of reactants. If the temperature is too high or too low, the reaction direction can be deviated and the product is impure. Uncomfortable pH also affects the reaction rate and yield. Improper proportion of reactants may lead to waste of raw materials or small amount of products. Second, other related compounds are also used as starting materials to build the desired structure through multi-step reactions. Every step of the reaction requires careful planning, the choice of reagents used, and the arrangement of the reaction sequence are all about success or failure.
After synthesis, it still needs to go through the process of separation and purification to obtain pure n-hydroxy-4-pyridinecarboximidamid. Column chromatography, recrystallization and other methods can be used to make the product reach the required purity.
Today's synthesis method is more efficient and accurate than the ancient method, but it also requires profound chemical knowledge and exquisite experimental skills.

N-Hydroxy-4-Pyriformamidine is a very important chemical substance. During use, many things need to be paid attention to.
First, safety protection should not be taken lightly. This substance may be toxic and irritating. When exposed, be sure to wear appropriate protective equipment, such as protective gloves, goggles and protective clothing, to avoid direct contact with the skin and eyes. If you come into contact inadvertently, rinse with plenty of water immediately and seek medical attention quickly according to the specific situation. The operation should be carried out in a well-ventilated environment, preferably in a fume hood to prevent inhalation of its dust or volatile gaseous substances, causing damage to the respiratory tract.
Second, storage should also be treated with caution. It should be stored in a dry, cool and ventilated place, away from fire and heat sources. At the same time, it should be stored separately from oxidants, acids, alkalis and other substances to avoid reactions. Due to its relatively active chemical properties, improper storage or deterioration can affect the use effect and even cause danger.
Third, when using, precise control of the dosage is extremely critical. According to specific experimental or production needs, with the help of accurate measurement tools, accurately weigh or measure the required amount to avoid affecting the reaction process and product quality due to too much or too little dosage. Furthermore, the reaction conditions must be strictly controlled, and many factors such as temperature, pH value, reaction time, etc. will have a significant impact on the reaction in which it participates. The appropriate reaction conditions should be clearly defined in advance, and closely monitored and regulated during operation to ensure the smooth progress of the reaction.
Fourth, after use, properly dispose of the remaining substances and waste. It should not be discarded at will, and should follow relevant environmental protection regulations to carry out harmless treatment to prevent pollution to the environment. The used appliances should also be cleaned in time to avoid residual substances affecting subsequent use.
Only by paying high attention to the above precautions and operating in strict accordance with regulations can we ensure the safety and efficiency of N-hydroxy-4-pyriformamidine during use.
