2-Methoxy-6-oxo-5,6,7,8-tetrahydro-quinoline-5-carboxylic acid methyl ester

This is the chemical structure of 2-methoxy-6-oxo-5,6,7,8-tetrahydroquinoline-5-carboxylic acid methyl ester. Its structure includes a quinoline parent nucleus, which undergoes a hydrogenation process at positions 5, 6, 7, and 8, resulting in partial saturation of the double bond, resulting in the formation of a tetrahydroquinoline structure. At position 2, there is a methoxy group, which is connected to the oxygen atom by the methyl group, and then to the quinoline parent nucleus. The sixth position is a carbonyl group, showing the structure of a carbon-oxygen double bond. The carboxyl group connected at position 5 is esterified with methanol to form a carboxylic acid methyl ester structure. This structure integrates the characteristics of quinoline compounds.

There are many ways to prepare 2-methoxy-6-oxo-5,6,7,8-tetrahydroquinoline-5-carboxylic acid methyl ester. First, we can start from common starting materials and borrow the magic method of organic synthesis. First, the compound containing quinoline parent nucleus is used as the base, and its structure is similar to the target product, but the required substituent is still lacking.
Methoxy can be introduced at a suitable check point in the parent nucleus through a specific reaction. This step often requires the selection of suitable reagents, such as methoxylation reagents, and under appropriate reaction conditions, such as specific temperatures and solvent environments, in order to make the reaction smooth and introduce methoxy groups precisely at the required check point.
Then, the construction of the tetrahydroquinoline structure can be achieved by reduction reaction. With a suitable reducing agent, the quinoline ring is partially hydrogenated and reduced in a certain reaction system to form a tetrahydroquinoline structure. In this process, the reaction conditions need to be carefully adjusted to prevent excessive reduction or side reactions.
As for the carboxyl methyl esterification step, esterification can usually be used. Using the corresponding carboxylic acid and methanol as raw materials, add suitable catalysts, such as concentrated sulfuric acid or specific Lewis acid. During the reaction, attention should be paid to the control of temperature and reaction time, so as to promote the full reaction of carboxylic acid and methanol to form the target carboxylic acid methyl ester structure.
In addition, there are other methods to follow. From different starting material combinations, by multi-step reactions, through functional group conversion, cyclization and other delicate steps, the complex structure of the target molecule can be gradually constructed, and finally 2-methoxy-6-oxo-5,6,7,8-tetrahydroquinoline-5-carboxylic acid methyl ester can be obtained.

2-Methoxy-6-oxo-5,6,7,8-tetrahydroquinoline-5-carboxylic acid methyl ester, the physical properties of this substance are as follows:
Looking at its properties, under normal temperature and pressure, or as a solid state, it also depends on the specific synthesis and refining conditions. The number of its melting point, due to the structural characteristics in the molecule, has a specific value, and it is rare to obtain accurate data. The molecule contains methoxy, carbonyl, ester and other functional groups, which make it have a certain polarity and may have a certain solubility in polar solvents. Alcohol solvents such as methanol and ethanol may have better solubility because their hydroxyl groups can form hydrogen bonds with the target molecules; while non-polar solvents, such as n-hexane and cyclohexane, have poor solubility. The boiling point of
is also determined by the intermolecular force, which is affected by the van der Waals force and the hydrogen bond. And because its structure contains a conjugate system, under the ultraviolet spectrum, when there is a characteristic absorption peak, it can be used for qualitative and quantitative analysis. In terms of density, although the exact value is unknown, according to the type and number of atoms in its structure, it can be inferred that its density should be similar to that of common organic compounds, slightly higher than or slightly smaller than water.
In addition, because it contains multiple reactivity check points, chemical properties or relatively active, under different reaction conditions, a variety of chemical reactions can occur, which may also have a certain impact on its physical properties.

I don't know the price of 2-methoxy-6-oxo-5,6,7,8-tetrahydroquinoline-5-carboxylic acid methyl ester in the market. The price of this product often changes for many reasons, and it cannot be said in a word.
First, the quality and quantity of the product have a great impact on the price. If its quality is high and the quantity is sufficient, and the supply is not in short supply, the price may be stable or reduced; however, if the quality is poor and the quantity is small, and the supply is in short supply, the price will rise.
Second, the amount of demand is also the key. If the industry is competing for this product to be used in the pharmaceutical and chemical industries, the price will rise if it is prosperous; on the contrary, if there is no need, the price will fall if it is weak.
Third, the cost of manufacturing also affects the price. The price of raw materials, manpower, equipment consumption, etc., are all entry fees. If the cost of manufacturing is high, the selling price is also high; if the cost of manufacturing is reduced, the price may be reduced.
Fourth, the competition in the market also plays a role. If there are many people competing for this product, and the competition is fierce, it is a competition for customers, or there is a price reduction; if there are few operators, it is close to a monopoly, and the price is easy to be high.
Due to the above-mentioned reasons, if you want to know the exact price of this product, you should consult the chemical raw material market, the chemical product trading platform, or negotiate with those who specialize in this industry to obtain a near-real-time price.
