3 + -Pyridinecarboxylic acid, 1, 2-dihydro-5-iodine-2-oxygen compound, the physical properties of this substance are as follows.
Its appearance or a specific color and shape. Generally speaking, it may be a crystalline solid, which can be orderly deposited into a crystalline state under suitable conditions due to the regular arrangement of atoms in the molecule. The color of this substance is different from that of ordinary pyridinecarboxylic acid derivatives due to the introduction of iodine atoms. The electronic structure of the iodine atoms makes it yellowish to light brown.
When it comes to the melting point, due to the complex intermolecular forces, including functional groups such as iodine atoms and carbonyl groups, which enhance the interaction between molecules, the melting point may be in a relatively high range, and it is speculated that it may be between 150 ° C and 250 ° C.
In terms of solubility, given the basicity of the pyridine ring and the acidity of the carboxyl group, it may have a certain solubility in polar solvents. In water, carboxyl groups can form hydrogen bonds with water molecules, but the hydrophobicity of iodine atoms and benzene rings limits the solubility in water, so the solubility in water may be limited; in organic solvents such as alcohols, due to the similar principle of compatibility, and alcohols can form hydrogen bonds with carboxyl groups, the solubility may be better than that of water.
Density is also an important physical property. Due to the presence of iodine atoms in the molecule, the relative mass of iodine atoms is large, resulting in a higher density than that of pyridinecarboxylic acid derivatives without iodine, or between 1.8 and 2.2 g/cm ³. The specific value depends on the exact molecular structure and crystal form.
Furthermore, it has a certain refractive index. The electron cloud distribution and chemical bond characteristics in the molecule cause light to refract when passing through. The refractive index can reflect the influence of the internal structure of the molecule on light propagation. Under specific conditions, the refractive index may be between 1.6 and 1.7, which can provide a basis for the identification of this substance.
In summary, 3 + -pyridinecarboxylic acid, 1,2-dihydro-5-iodine-2-oxygen, with its unique physical properties, lays the foundation for research and application in related fields.

5-Iodine-1,2-dihydro-2-oxo-3-pyridinecarboxylic acid, which has strange physical properties and is common to acids. It can be weakly ionized in water and release hydrogen ions, which is acidic. Its structure is unique. The iodine atom is connected to the pyridine ring, and there are dihydrogen and oxygen groups on the ring, which makes its chemical activity unique.
When it comes to the reaction characteristics, carbonyl groups can be involved in many reactions. In the case of nucleophiles, carbonyl carbons can undergo addition reactions when attacked by nucleophiles. They can form esters with alcohols and amides with amines. The activity of iodine atoms should not be underestimated. They can participate in the substitution reaction and be replaced by other groups, and then derive a variety of compounds.
Its solubility is quite special, because it contains carboxyl groups, it has a certain solubility in polar solvents such as water, but the pyridine ring and iodine atom increase its hydrophobicity, resulting in its solubility is not very high. When heated, the molecular structure may change, decompose, or rearrange, depending on temperature and environment.
In addition, the compound may have certain biological activity and may have potential uses in the fields of medicine and pesticides, but its specific activity remains to be further explored.

To prepare 3-pyridinecarboxylic acid, 1,2-dihydro-5-iodine-2-oxo, follow the following ancient method.
First take pyridine as the base, and introduce iodine atoms at the 5th position through a specific halogenation method. This halogenation method selects suitable halogenating reagents, such as iodine in combination with an appropriate oxidizing agent, in a specific reaction environment, control its temperature and duration, so that iodine atoms are precisely added to the 5th position of the pyridine ring to obtain 5-iodine pyridine.
Then, 5-iodine pyridine is oxidized to form a 2-oxo structure. Select an appropriate oxidizing agent, such as a reagent with suitable oxidation ability, in a suitable solvent system, adjust the reaction conditions, so that the pyridine ring forms a double bond between the 1,2 positions, and the 2 positions are oxidized to a carbonyl group to obtain 1,2-dihydro-5-iodine-2-oxo pyridine. After
, carboxylation of 1,2-dihydro-5-iodine-2-oxo pyridine is performed. A specific reaction path can be used, such as using a suitable reagent to interact with the substrate, in a suitable reaction vessel, under temperature control, pressure and other conditions, the pyridine ring is introduced into the carboxyl group at the 3rd position, and the final product is 3-pyridinecarboxylic acid, 1,2-dihydro-5-iodine-2-oxo-target product.
The whole reaction process requires careful monitoring of each step, and the reaction progress and product purity are determined by analytical methods, such as chromatography, spectroscopy, etc. And the control of the reaction conditions at each step is crucial to the yield and purity of the product.

I think what you are asking about 3 + -pyridinecarboxylic acid, 1,2-dihydro-5-iodine-2-oxo is in the market price range. However, when this product is in the market, its price often changes due to various reasons, and it is difficult to say exactly.
Bearing the brunt, the price of raw materials has a great impact. If the price of all raw materials required for its preparation rises and falls, the price of this product will also change accordingly. If the starting material for preparing this pyridinecarboxylic acid derivative, if the output increases or decreases, the origin changes, and the supply and demand imbalance, the price will rise or fall, and it will be transmitted to the final product.
Furthermore, the simplicity of the preparation process is also the key. If the preparation requires complex and delicate steps, multiple reactions, purification, and a huge cost of manpower, material resources, and time, the cost will be high and the price will be high. On the contrary, if the process is simple and mature, the cost is controllable, and the price may be slightly lower.
The state of market supply and demand also affects its price. If the market demand for this product is strong and the supply is limited, merchants may raise the price to obtain a big profit; if the supply exceeds the demand, merchants will sell inventory or reduce the price for promotion.
In addition, factors such as the manufacturer's brand and product purity also play a role. Well-known manufacturers and high-purity products may have higher prices than ordinary ones.
Roughly speaking, this 3 + -pyridinecarboxylic acid, 1,2-dihydro-5-iodine-2-oxo substitute, at the market price or in the range of tens to hundreds of yuan per gram. However, this is only a rough estimate. The actual price needs to be consulted with the relevant chemical raw material suppliers in detail, and the exact quotation can be obtained according to the specific specifications and quantities.
