The synthesis of 6-cyano-1,4-dihydro-4-oxyquinoline-2-carboxylic acid methyl ester requires a chemical reaction process of several steps. The choice of starting materials is crucial to the success or failure of the synthesis. Quinoline derivatives with specific substituents are often used as starting materials, which can be commercially available or made according to existing organic synthesis methods.
The first step may require the introduction of a cyanide group. A suitable cyanide reagent, such as potassium cyanide or sodium cyanide, can be selected to interact with the starting quinoline derivative under specific reaction conditions. This reaction may need to be carried out in an organic solvent, such as dimethylformamide (DMF) or dichloromethane, and appropriate alkali substances are required to facilitate the reaction. The alkali can be selected from potassium carbonate or sodium carbonate, etc. Its function is to assist the cyanyl group to replace the functional group at a specific position, so as to introduce the cyanyl group at the 6 position of the quinoline ring.
Second steps to construct a 1,4-dihydro-4-oxo structure. This step often requires oxidation and cyclization reaction steps. A suitable oxidizing agent, such as manganese dioxide or chromium trioxide, can be used to oxidize the quinoline derivative under appropriate solvent and temperature conditions to form a specific unsaturated ketone structure. Then, the structure of 1,4-dihydro-4-oxo generation is achieved by intramolecular cyclization reaction. The cyclization reaction may require specific catalysts, such as concentrated sulfuric acid or Lewis acid, to promote intramolecular rearrangement and cyclization.
The last step is to form a methyl ester. In this step, methanol and suitable esterification reagents, such as dichlorosulfoxide or oxalyl chloride, can be selected. First, esterification reagents react with 6-cyano-1,4-dihydro-4-oxyquinoline-2-carboxylic acid to form an active acid chloride intermediate, and then this intermediate reacts with methanol to obtain the target product 6-cyano-1,4-dihydro-4-oxyquinoline-2-carboxylic acid methyl ester. After the reaction, the separation and purification steps are required to obtain a purified product. Commonly used separation methods include column chromatography or recrystallization to ensure that the purity of the product meets the requirements.

I look at your question, but I am inquiring about the market price of 6-cyano-1,4-dihydro-4-oxyquinoline-2-carboxylic acid methyl ester. However, the price of this product often changes due to many reasons, and it is difficult to determine a certain number.
First, the supply is different, and the price is different. If you get it from a good factory, the quality will be high or high; if you source from an ordinary manufacturer, the price may be slightly lower. Second, the quantity also affects the price. If you buy a large quantity, you may be given a discount, and the price is low; if you buy a small quantity, the price may be high. Third, the price varies depending on the time. Market supply and demand change, and prices follow suit. When the demand is high, the price tends to rise; when the supply is high, the price tends to fall.
As far as I know, the price of this chemical in the market may range from tens to hundreds of yuan per gram. If the purchase quantity exceeds 100 grams, the price per gram may drop to tens of yuan. However, this is only a rough estimate. The actual price should be consulted with the chemical supplier, and his quotation shall prevail. If you want to know the exact price, you can check it in detail on the chemical product trading platform, or directly ask the relevant merchants to get the accurate price.

6-Cyano-1,4-dihydro-4-oxo-quinoline-2-carboxylic acid methyl ester, this is an organic compound. Its storage conditions are crucial to its stability and quality.
