What are the Physical and Chemical Properties of Azetidine Sulfonic Acid?
Azacyclobutane sulfonic acid is a kind of compound with both azacyclobutane structure and sulfonic acid group. Its physical and chemical properties are unique and have important uses in many fields.
In terms of its physical properties, azacyclobutane sulfonic acid is mostly in solid form, and its appearance is often white to light yellow powder. This is due to the intermolecular force that causes the crystallization characteristics to be so. Its melting point is relatively high, and due to the strong polarity of the sulfonic acid group and the stability of the azacyclobutane ring, it requires high energy to break the lattice structure. And such compounds have good solubility in water, and the strong hydrophilicity of the sulfonic acid group makes it easy to form hydrogen bonds with water molecules, which in turn promotes dissolution. However, in organic solvents, the solubility varies according to the properties of the solvent. For example, the solubility is better in polar organic solvents, but worse in non-polar solvents.
In terms of chemical properties, the sulfonic acid group is highly acidic, which can ionize hydrogen ions in aqueous solutions, showing the characteristics of typical acids, which can neutralize with bases to generate corresponding salts. The nitrogen heterocyclic butane ring has certain reactivity, and the existence of ring tension makes it prone to ring-opening reactions. When encountering nucleophiles, nucleophiles can attack the carbon atoms on the ring, causing the ring to open and form new compounds. At the same time, the nitrogen atom of the compound has a lone pair of electrons, which can be used as a ligand to coordinate with metal ions to form a stable complex, which is of great significance in the field of catalysis and materials science. In addition, the chemical stability of nitrogen heterocyclic butane sulfonic acid is quite high, and it is not easy to decompose under normal conditions. However, under extreme conditions such as strong acid, strong base or high temperature, its structure may change.
What are the Synthetic Methods of Azetidine Sulfonic Acid
There are many ways to synthesize azitidine sulfonic acid (Azetidine Sulfonic Acid).
First, it can be started from a suitable nitrogen-containing heterocyclic precursor. For example, select an nitrogen-heterocyclic butane derivative with an appropriate substituent group to react with a sulfonic acid-containing reagent. A nucleophilic substitution reaction can be used. If there is a suitable leaving group on the nitrogen-heterocyclic butane derivative, such as a halogen atom, etc., the sulfonate anion is used as a nucleophilic reagent to attack the carbon site where the leaving group is located. Through the nucleophilic substitution process, a carbon-sulfur bond is formed, and a sulfonic acid group is introduced to obtain the target product azicyclic butane sulfonic acid. This process requires attention to the regulation of reaction conditions. Temperature, solvent and other factors will affect the rate and selectivity of the reaction. Appropriate polar solvents, such as dimethyl sulfoxide (DMSO) or N, N-dimethylformamide (DMF), should be selected to promote the reaction between ions. The temperature should also be precisely controlled. If it is too low, the reaction will be slow, and if it is too high, it will cause side reactions.
Second, the strategy of gradually building the ring system can be adopted. First, the ternary ring skeleton containing nitrogen is constructed by organic synthesis, and then the sulfonic acid group is introduced. For example, through a suitable bifunctional compound, the intramolecular cyclization reaction forms an azacyclobutane structure. The sulfonation reaction is then used to sulfonate the obtained azacyclobutane with sulfonating reagents such as concentrated sulfuric acid, fuming sulfuric acid or chlorosulfonic acid, and a sulfonate group is introduced into the ring. However, when using such sulfonating reagents, the reaction activity is quite high, and it is necessary to operate with caution and strictly control the reaction conditions to prevent excessive sulfonation or other side reactions. Or a milder sulfonation method can be used, such as the use of sulfonolactone reagents, to achieve the introduction of sulfonate groups under relatively mild conditions to improve the controllability and selectivity of the reaction.
Third, the method of catalytic synthesis can also be selected. With the help of specific catalysts, the reaction can be promoted. Such as metal catalysts or small organic molecule catalysts, which can reduce the activation energy of the reaction and accelerate the reaction process. For example, some transition metal complex catalysts can activate the reaction substrate, so that the reaction that was originally difficult to occur can proceed smoothly. In the synthesis of azacyclobutane sulfonic acid, the catalyst can be used to selectively promote the formation of nitrogen-containing rings and sulfonic acid groups, while reducing unnecessary side reactions and improving the purity and yield of the product. However, suitable catalysts need to be carefully screened, taking into account their adaptability to the substrate, catalytic activity and selectivity.
What is the price range of Azetidine Sulfonic Acid in the market?
I look at your question, but I am inquiring about the price range of nitrogen heterocyclic butane sulfonic acid in the market. However, the price of this substance is difficult to determine, due to many factors.
First, its purity has a great impact. If the purity is extremely high, it is suitable for high-end scientific research or fine chemicals, and the price must be high; if the purity is slightly lower, it is only for general experimental or basic industrial use, and the price may be slightly reduced.
Second, the manufacturer and the origin are also related. Well-known large factories, due to exquisite craftsmanship and stable quality, their price may be higher than that of small factories; different origins, due to differences in raw material costs and transportation conditions, the price is also different.
Third, the market supply and demand situation is the key. If there are many people who want it, the supply will be few, and the price will rise; on the contrary, if the supply exceeds the demand, the price will decline.
Furthermore, the packaging specifications also have different prices. For large packages, the unit price may be more affordable; for small packages, due to packaging costs and other factors, the unit price may be slightly higher.
Generally speaking, in the scientific research reagent market, the purity of nitrogen heterocyclic butane sulfonic acid ranges from tens of yuan to 100 yuan per gram; in the industrial raw material market, when purchasing in bulk, the price per ton may be between tens of thousands and hundreds of thousands of yuan. However, this is only a rough estimate. The actual price needs to be consulted with the supplier in detail, and various factors can be considered comprehensively to obtain an accurate price.
