2-% Hydroxy-7-methoxycoumarin (8CI) is an important organic compound with the following physical properties:
- ** Appearance and Properties **: Usually in the state of white to pale yellow crystalline powder, the texture is fine, and the regular crystalline structure can be seen under the microscope. This morphology is derived from the specific arrangement and action forces between molecules. In the solid state, the stable structure is maintained by intermolecular hydrogen bonds and van der Waals forces.
- ** Melting Point and Boiling Point **: The melting point is about 185-188 ° C. At this temperature, the molecule is energized enough to overcome the lattice energy, and the lattice structure disintegrates and converts from a solid state to a liquid state. The boiling point is difficult to accurately determine because the substance reaches the boiling point or decomposes. However, it can be inferred that due to the existence of hydrogen bonds and other interactions between molecules, the boiling point is relatively high.
- ** Solubility **: Slightly soluble in water, although there are hydroxyl groups in its molecules that can form hydrogen bonds with water, but the parent nucleus of coumarin and methoxy groups are hydrophobic groups, resulting in poor overall water solubility. However, it can be better dissolved in organic solvents such as methanol, ethanol, and acetone. In these solvents, the solute and solvent molecules interact with van der Waals forces, hydrogen bonds, etc., and disperse uniformly to form a stable solution.
- ** Odor **: It has a weak aromatic odor, which is derived from the structural characteristics of coumarins. Its volatility is low, and the odor is slow to emit, which can only be detected by close sniffing. < Br > - ** Density **: The density is about 1.35 g/cm ³, which reflects the degree of tight packing of molecules. Due to the molecular structure containing benzene ring, lactone ring and methoxy group, the spatial arrangement is compact and the density is high.

2-Amino-7-chloroquinolinopyridine (8CI) is a kind of organic compound. Its chemical properties are unique and of great research value.
In terms of its physical properties, it often appears as a solid state, and the color may be white to light yellow. The genus of melting point and boiling point is specific due to the interaction between atoms in the molecular structure. The atoms in the molecule are connected by covalent bonds and have a stable structure. The force of this covalent bond makes the molecule have a specific geometric configuration, which has a profound impact on its physical and chemical properties.
In terms of its chemical properties, the amino group is an active functional group and has a basic nature. The lone pair electrons on the nitrogen atom can bind protons and easily form salts in acidic environments. This property enables 2-amino-7-chloroquinolinopyridine (8CI) to react with acids to form corresponding salts.
Furthermore, chlorine atoms also play an important role in molecules. Its electronegativity is large, which makes the distribution of molecular electron clouds uneven, and the electron cloud density of ortho or para-carbon atoms changes, resulting in an increase in the activity of this position, which is prone to nucleophilic substitution reactions. Nucleophilic reagents can attack the carbon atoms attached to the chlorine atoms, and the chlorine atoms leave to form new compounds.
The dense ring structure of quinolinopyridine gives it aromaticity. Due to the existence of the conjugate system, the electrons are delocalized and the structure is stable. However, it also makes the molecule rigid, which affects its solubility and reactivity. Because the conjugated system can participate in the electron transfer process, under the conditions of light, electricity, etc., or exhibit special chemical behaviors, such as participating in photochemical reactions, to generate products with unique structures and properties.
In summary, 2-amino-7-chloroquinolinopyridine (8CI) presents a variety of chemical properties due to its functional groups and fused ring structures, and has potential application value in organic synthesis, pharmaceutical chemistry and other fields.

To prepare 2-amino-7-sulfonic acid pyridine (8CI), the method is as follows:
First, the corresponding pyridine derivatives can be prepared by amination and sulfonation sequence. First, take a suitable pyridine parent, under specific reaction conditions, with ammonia or amino-containing reagents, under suitable catalysts, temperatures and pressures, conduct amination reactions to introduce amino groups. Then, select appropriate sulfonating agents, such as concentrated sulfuric acid, fuming sulfuric acid, etc., at appropriate temperatures and reaction times, sulfonate specific positions on the pyridine ring, and then obtain the target product. This process requires precise control of the reaction conditions to prevent side reactions from reducing the purity of the product. < Br >
Second, it is prepared by multi-step cyclization reaction with nitrogen-containing and sulfur-containing raw materials. The starting material undergoes a series of reactions such as condensation and cyclization to build a pyridine ring structure. At the same time, amino and sulfonic acid groups are introduced. For example, nitrogen-containing organic compounds and sulfur-containing reagents, under the catalysis of bases or acids, first condensate to form an intermediate product. The intermediate product is induced by heating or other conditions to cyclize within the molecule and gradually generate 2-amino-7-sulfonic acid and pyridine. The key to this path is to design a reasonable reaction route to ensure that the reaction proceeds smoothly and the yield is considerable.
Third, biosynthesis can also be considered. With the help of some microorganisms or enzymes, the target product is synthesized by enzymatic reaction starting with a specific substrate. This method is environmentally friendly and has good selectivity, but it needs to screen suitable microorganisms or enzymes and optimize biological reaction conditions, such as temperature, pH value, substrate concentration, etc., to achieve efficient biosynthesis.

In today's market, the price of 2-amino-7-chloroquinoline (8CI) probably varies depending on its quality and the supply and demand of the market.
If its quality is pure, it is urgent for various industries, and the price must be high; if the quality is inferior and the supply exceeds the demand, the price may be low. However, if you want to know the price of its domain, it is difficult to determine by a few words.
Looking at all kinds of business conditions, if this agent is required for the production of good medicines in pharmaceutical companies, and the market demands it, the price may range from tens of gold to hundreds of gold per catty. If it is used in ordinary chemical industries and the market supply is abundant, each catty or only a few tens of gold. < Br >
The rise and fall of the price of the cover depends on the width of its use, the amount of its requirements, and the purity of its quality. In order to know its exact price, it is necessary to observe the situation of the city and visit the people to obtain its approximate price range.
