4-Hydroxypyridine-3-Sulfonic the chemical properties of Acid

4-Hydroxypyridine-3-sulfonic acid is one of the organic compounds. It has unique chemical properties. As far as acidity is concerned, because it contains sulfonic acid groups (-SO-H) and hydroxyl groups (-OH), the sulfonic acid group is a strong acidic group, which can ionize hydrogen ions in water, causing it to be acidic. And this acidic group is stronger than the hydroxyl acid of general phenols, and the electron-absorbing effect of the cover sulfonic acid group enhances the activity of hydroxyl hydrogen.
When it comes to reactivity, sulfonic acid groups can undergo various reactions. For example, it can form salts with bases and be esterified with alcohols to form sulfonates. In this esterification reaction, the hydroxyl group of the sulfonic acid group dehydrates and condenses with the hydroxyl group of the alcohol. Hydroxyl groups can also participate in the reaction, and can react with acid chloride or acid anhydride to acylate and form ester derivatives.
Its pyridine ring also has characteristics. Pyridine ring has certain aromatic properties and can undergo electrophilic substitution reaction.

And 4-hydroxypyridine-3-sulfonic acid can be used as a ligand, and the lone pair of electrons of nitrogen atom and hydroxyl group coordinate with metal ions to form complexes, which have potential applications in catalysis, materials science and other fields. Its stability is enhanced by intramolecular hydrogen bonds and conjugation effects. The conjugate system delocalizes electrons, reduces molecular energy, and makes its chemical properties relatively stable. However, under certain conditions, various chemical reactions can still occur, exhibiting its diverse chemical behaviors.

What is the production method of 4-Hydroxypyridine-3-Sulfonic Acid?

The method of making 4-hydroxypyridine-3-sulfonic acid has been used in ancient times. The method is based on chemical principles and uses various raw materials and techniques.
In the past, this product was often based on pyridine. First sulfonate pyridine, and choose a suitable sulfonating agent, such as concentrated sulfuric acid or fuming sulfuric acid. At an appropriate temperature and reaction time, pyridine can interact with the sulfonating agent to introduce a sulfonic acid group to obtain pyridine-3-sulfonic acid.
Then, pyridine-3-sulfonic acid is hydroxylated. In this step, oxidizing agents, catalysts, etc. are used to replace the hydrogen in the ortho-position of the sulfonic acid with hydroxyl groups. The oxidizing agent used can be hydrogen peroxide, etc.; the catalyst varies according to the specific reaction. During the reaction, control the temperature, pressure and pay attention to the proportion of the reactants, and even matters that matter.
There are also other methods. Or introduce other groups at a specific position of pyridine first, and then convert them into hydroxyl and sulfonic acid groups through a series of reactions. This requires a good understanding of the reaction mechanism of each step and precise control of the conditions of each step to obtain high-purity 4-hydroxypyridine-3-sulfonic acid.
All kinds of production methods require fine operation and strict control of conditions in order to achieve satisfactory results. In industrial and scientific research, they all seek efficient, stable and pure products.

What is the price range of 4-Hydroxypyridine-3-Sulfonic Acid in the market?

The price range of 4-hydroxypyridine-3-sulfonic acid in the market is difficult to determine. This is because the price is often influenced by many factors, such as quality, supply and demand situation, production process simplicity, and differences in merchants.
The price of the market in the past may vary due to different purity. If the purity is high, it can reach a very high standard, and it is suitable for high-demand fields such as fine chemicals and pharmaceutical research and development, the price should be very high. Because the preparation of such high-purity products requires exquisite craftsmanship and huge cost. Its price per kilogram may reach hundreds or even thousands of yuan.
However, if the purity is slightly lower, it is only for general industrial use, and its price may be relatively easy.
Moreover, the relationship between supply and demand has a great impact on the price. If the market demand is strong and the supply is limited, the merchant may raise the price; conversely, if the supply exceeds the demand, the price may be reduced for promotional sales.
The production process is also the key. Novel, efficient and low-cost processes may make the product price more competitive; outdated and complicated methods, the cost is high, and the price is difficult to reduce.
As for the pricing strategies of each merchant, there are also differences. Or due to factors such as brand reputation and service quality, the price shows differences. Therefore, in order to determine the exact price range of 4-hydroxypyridine-3-sulfonic acid, it is necessary to carefully investigate the latest market trends and consult many suppliers to obtain accurate market conditions.
