The structure of this compound can be disassembled and analyzed from its name. " (3S) " shows its three-dimensional configuration, which has a specific arrangement in space, just like the stars have their positions in the sky. " 9,10-Dihydro "indicates that between the carbon atoms at position 9 and 10, the original unsaturated bond is saturated due to hydrogenation, just like a stream converges and returns to calm." 3-methyl "refers to the methyl group attached to the carbon atom at position 3, such as the oblique branch next to the branch." 7-oxo "refers to the double bond between the carbon atom at position 7 and the oxygen atom to form a carbonyl group, which gives the molecule a unique chemical activity, like the hub of a chemical reaction." 2,3-dihydro "also indicates that the carbon atoms at positions 2 and 3 undergo hydrogenation changes." 7H - [1,4] diazanaphthalene and [2,3,4 - ij] quinoline "describes a fused ring system composed of multiple rings that are combined with each other, just like a carefully built pavilion, each ring is interdependent." 6-carboxylic acid "indicates that there is a carboxyl group connected at the 6 position, and the carboxyl group is an acidic functional group that affects the many properties of the compound. It is like a key that opens the door to many chemical reactions.
Its overall chemical structure is an orderly combination of these parts, and the interaction of each part gives this compound its unique physical and chemical properties, which is unique in the field of organic chemistry.

(3S) -9,10 -dihydro-3-methyl-7-oxo-2,3-dihydro-7H - [1,4] naphthaleno [2,3,4-ij] furan-6 -carboxylic acid, this substance has the following physical properties:
1. ** Appearance **: Usually in solid form, but the specific appearance may vary depending on the preparation method and purity. Generally, it is white to off-white crystalline powder. When observed under a microscope, its crystals may exhibit regular or irregular shapes.
2. Melting point: Melting point is one of its important physical properties. Accurate melting point values are crucial for the identification of the compound. However, the specific melting point needs to be accurately measured by a professional melting point tester. Common melting point ranges of such compounds may be within a certain range, such as [specific melting point range] (here, because accurate data is not found, it is only an example). This property can be used to judge the purity of the substance. If the purity is high, the melting point range is relatively narrow. Otherwise, the melting point may be offset and the range is widened.
3. ** Solubility **: The solubility varies in different solvents. In polar organic solvents such as ethanol and methanol, it may have a certain solubility and can partially dissolve to form a homogeneous solution, because of the interaction between some groups in its molecular structure and these polar solvent molecules, such as hydrogen bonds; while in non-polar solvents such as n-hexane and toluene, the solubility is poor and basically insoluble, which is related to the mismatch between the polarity of the molecule and the polarity of the solvent. The solubility in water is also poor, because the hydrophobic part of the molecule is relatively large, it is not easy to form effective interactions with water molecules.
4. ** Density **: Density is of reference value for the application of this compound in some technological processes. Although the exact density needs to be determined experimentally, it is inferred from the structure that its density should be between the density ranges of some common organic compounds, such as [approximate density range] (example), which is helpful for relevant calculations when involving mixing, separation, etc. of substances.
5. ** Stability **: It is relatively stable under normal temperature and pressure, protected from light, and dry conditions. However, if exposed to strong light, high temperature, or high humidity, decomposition reactions may occur. Some functional groups in its molecular structure, such as carbonyl groups, double bonds, etc., may undergo chemical reactions under specific conditions, resulting in structural changes of the compound, affecting its chemical and physical properties.

The preparation method of (3S) -9,10-dihydro-3-methyl-7-oxo-2,3-dihydro-7H- [1,4] oxazino [2,3,4-ij] phenoxazine-6-carboxylic acid is as follows:
First, take an appropriate amount of starting materials and place them in a clean kettle. In the ancient method, it is necessary to ensure that the kettle is clean and free of impurities to prevent the raw materials from being contaminated and causing the reaction to fail to meet expectations.
Add a specific reagent and solvent to the kettle. The amount of this reagent and solvent needs to be precisely controlled, just like the ancient method of alchemy, the slightest difference may cause the whole plate to be lost. Stir well to make the raw materials and reagents fully blend, just like the ancients blended all kinds of medicinal stones.
Then, slowly raise the temperature of the kettle to a suitable range. The regulation of this temperature is extremely critical. If it is too high, the raw materials may be destroyed, and if it is too low, the reaction will be slow. Just like the heat of alchemy, it needs to be just right. During the heating process, continue to stir to heat the things in the kettle evenly.
When the reaction is going on, it is necessary to closely observe the changes in the kettle, just like the ancients watching the alchemy furnace intently. Check the reaction process in a timely manner, according to the test results, or adjust the temperature, or add an appropriate amount of additives to ensure the smooth progress of the reaction.
When the reaction is completed, cool the things in the kettle to room temperature. After that, the target product is separated from the reaction mixture by suitable separation means, such as filtration, extraction, etc. This process needs to be meticulous to prevent the loss of the product.
Finally, the separated product is purified, such as recrystallization, to obtain high purity of (3S) -9,10-dihydro-3-methyl-7-oxo-2,3-dihydro-7H - [1,4] oxazino [2,3,4-ij] phenoxazine-6-carboxylic acid. The purification steps should not be sloppy, and the products should be as pure and flawless as the ancients carefully carved utensils.
