What is the production method of 6-aminonaphthalene-2-sulfonic acid?

6-Aminopurine-2-ketoacid, that is, 6-aminopurine-2-ketoacid, which is also known as isoguanine. Although its preparation method is difficult to find in ancient records, it can be deduced from ancient possible methods with modern chemical knowledge.
To make 6-aminopurine-2-ketoacid, you can first take purine-based basic substances. Although there is no modern advanced purification technology in ancient times, it can be extracted from natural substances rich in purines, such as certain beans and meats that have been boiled, precipitated, and filtered for a long time, or crude products containing purines can be obtained.
Start with the crude purine product. If you want to introduce amino groups into its 6 positions, you can use the method of amination. Although there were no modern chemical reagents in ancient times, natural nitrogen-containing substances such as ammonia water could be used. The crude purine product and ammonia water are placed in a sealed container together, and after proper heating, the substitution reaction between ammonia and purine can be promoted. The amino group is introduced at the 6 position to obtain 6-aminopurine.
Then, if you want to form a ketoacid structure at the 2 position, you can use oxidation and carboxylation reactions. Although there were no precise oxidation reagents in ancient times, you can use oxygen in the air to use specific metal oxides as catalysts to promote the oxidation of 6-aminopurine at the 2 position to generate the corresponding carbonyl structure. Then, carbon dioxide and other carbon-containing substances are used to react with the oxidation product under alkaline conditions, and the carboxyl group is introduced at the second position, and finally 6-aminopurine-2-ketoacid is obtained.
The whole process requires precise control of temperature, reaction time, and the proportion of reactants. Although the ancient technology is simple, this substance may be obtained through experience accumulation and repeated attempts. This is only a speculation on the ancient preparation method based on modern chemical principles, and may be deviated from reality.

What should be paid attention to when storing and transporting 6-aminonaphthalene-2-sulfonic acid?

When hiding and using it, there are things to pay attention to when it comes to hexaaminopurine-2-ketoacid.
When hiding, it is the first environment. This acid should be placed in a cool, dry and well-ventilated place, away from direct sunlight. The heat and light of sunlight can initiate its chemical reaction and cause it to deteriorate. And it needs to be kept away from fire and heat sources to prevent unexpected risks. In addition, sealing is also necessary. A sealed device can keep air, moisture and impurities out and keep its chemical properties stable. If using glass or plastic, seal it tightly and do not allow gas and liquid to leak.
When using, safety comes first. It is necessary to wear protective equipment, such as gloves, goggles, masks, etc., because it may be irritating to the skin, eyes, and breathing. The operation should be done in a well-ventilated place or in a fume hood to avoid the accumulation of harmful gases. The control of the amount should not be ignored. Before use, the dosage must be accurately measured, and it should be done according to the instructions. Do not exceed or lack, otherwise it will affect the effect.
The order of mixing is also important. When incorporating other substances, add them slowly, and accompany them with stirring to disperse evenly, so as to avoid excessive reaction caused by excessive local concentration. If it is used in combination with other drugs or reagents, it must first be detailed about its chemistry to see if it is compatible and reactive, so as to prevent adverse reactions.
After use, it should not be light. Residual liquid and waste should be disposed of according to regulations, and should not be disposed of at will, to prevent pollution of the environment. The device should also be cleaned for reuse. In this way, be careful when hiding and using it, so that the quality of hexaaminopurine-2-ketoacid can be maintained, and it can be used without worry.
