To prepare 4-amino-2-pyridinecarboxylic acid hydrochloride, the method is as follows. Take 2-pyridinecarboxylic acid as the starting material, and use appropriate reagents and conditions to make it nitrate. This step requires careful selection of reaction temperature, solvent and nitrifier. Usually a mixed acid system of nitric acid and sulfuric acid can be used, and the temperature can be controlled to make the reaction proceed in the direction of generating 4-nitro-2-pyridinecarboxylic acid.
After 4-nitro-2-pyridinecarboxylic acid is obtained, the nitro group is converted to amino group by reduction. There are many reducing agents available, such as a system composed of metals and acids, such as iron and hydrochloric acid. In this system, iron is eroded by acid to produce new hydrogen. This active hydrogen can gradually reduce the nitro group to an amino group, resulting in 4-amino-2-pyridinecarboxylic acid.
Finally, 4-amino-2-pyridinecarboxylic acid is interacted with hydrochloric acid, and under suitable temperature and concentration conditions, the amino group is combined with the hydrogen ion of hydrochloric acid to form the corresponding hydrochloride, which is 4-amino-2-pyridinecarboxylate hydrochloride. Throughout the process, the reaction conditions at each step need to be precisely controlled in order to obtain a product with higher yield and purity.

4-Amino-2-pyridinecarboxylate hydrochloride, this is a chemical substance, and many matters need to be carefully paid attention to during storage and transportation.
Let's talk about storage first. First, it needs to be placed in a cool place. Because the temperature is too high, or the properties of the substance may change, causing a chemical reaction and damaging its quality. Second, it should be kept in a dry environment. Because of its certain hygroscopicity, it is easy to deliquescent in case of moisture, which will affect the purity and performance, it should be stored in a dry and well-ventilated place, away from water sources and humid corners. Third, it should be sealed and stored. Avoid contact with air to prevent oxidation or reaction with components in the air, and sealing can block odor interference. Fourth, you must also pay attention to keep away from fire sources, heat sources and strong oxidants. This substance may be flammable or react violently with oxidants, endangering safety.
As for transportation, the first thing to ensure is that the packaging is intact and firm. This can prevent package damage during transportation, cause material leakage, and endanger the environment and personal safety. Second, the means of transportation should be clean and pollution-free. If there are other chemical residues, or react with 4-amino-2-pyridinecarboxylate hydrochloride. Third, the transportation process also needs to be temperature-controlled, moisture-proof, maintain a suitable environment, follow relevant transportation regulations and standards, and a special person is responsible for supervision to ensure safe transportation.

I look at the market price range of 4 - Amino - 2 - pyridinecarboxylic acid hydrochloride. This is a product in the field of fine chemicals, and its price often varies depending on quality, purity, supply and demand, and market conditions.
In the past in the world of "Tiangong Kaiwu", although there is no such modern fine chemical product, it can be known that the price of the product varies according to many factors. Today, if the purity of this compound is ordinary, the price per gram may be in the tens of yuan. However, if it is of high purity, such as used in high-end fields such as pharmaceutical research and development, its price may rise sharply, reaching hundreds of yuan per gram.
In the chemical raw material market, when purchasing in bulk, due to the scale effect, the unit price may be discounted. And due to regional differences, such as coastal chemical industry developed, the supply is sufficient, the price may be slightly lower; inland remote places, due to transportation costs, the price may be slightly higher. Overall, the market price range of 4 - Amino - 2 - pyridinecarboxylic acid hydrochloride is tens of yuan per gram for ordinary purity and hundreds of yuan per gram for high purity. Bulk procurement and regional differences also affect its price.
