This is a rather complex organic compound that exhibits unique physical properties due to its specific chemical structure and functional groups.
Its appearance may be white to light yellow crystalline powder, which is orderly due to the regular molecular structure and intermolecular forces. And this compound has a certain melting point, or the transition from solid to liquid state occurs in a specific temperature range. This is due to the increase in temperature, which intensifies the thermal movement of molecules and destroys the crystal structure. < Br >
In terms of solubility, it may have a certain solubility in organic solvents such as ethanol and chloroform. Due to the principle of similar miscibility, the organic structure of the compound has a certain affinity with organic solvents; while in water, the solubility may be limited, because the hydrophobic groups in the molecule account for a large proportion, reducing the ability to interact with water molecules.
The density of the compound is moderate, neither extremely light nor extremely heavy, which is determined by its molecular composition and relative molecular weight. In addition, due to the structure of benzopyran and pyridine, it may have certain stability, but under extreme conditions such as strong acid, strong base or high temperature, the molecular structure may be destroyed and chemical reactions occur.
The unique physical properties of this compound are closely related to its structure, and their applications in chemistry, medicine, and other fields may be determined by these properties.

To prepare 3-pyridinecarboxylic acid, (2S) -3,4-dihydro-2,5,7,8-tetramethyl-2-[ (4R, 8R) -4,8,12-trimethyltridecyl] -2H-1-benzopyran-6-yl ester, there are many methods for its synthesis.
First, you can take (2S) -3,4-dihydro-2,5,7,8-tetramethyl-2-[ (4R, 8R) -4,8,12-trimethyltridecyl] -2H-1-benzopyran-6-ol and make it react with 3-pyridyl formyl chloride in a suitable base, such as pyridine or triethylamine, in an inert solvent, such as dichloromethane or chloroform, at low temperature to room temperature. In this process, the hydroxyl group of the alcohol undergoes nucleophilic substitution with the acyl group of the acid chloride, thereby forming the target ester. The function of the base is to absorb the hydrogen chloride generated by the reaction and promote the forward reaction.
Second, 3-pyridinecarboxylic acid and (2S) -3,4-dihydro-2,5,7,8-tetramethyl-2-[ (4R, 8R) -4,8,12-trimethyltridecyl] -2H-1-benzopyran-6-ol are used as raw materials, using a condensing agent such as dicyclohexyl carbodiimide (DCC) and 4-dimethylaminopyridine (DMAP) as a catalyst to react in organic solvents such as dichloromethane or tetrahydrofuran. DCC can activate carboxylic acids to make them more susceptible to esterification with alcohols, while DMAP can accelerate the reaction process and improve the reaction efficiency.
Furthermore, 3-pyridinecarboxylic acid can be converted into the corresponding active ester, such as p-nitrophenyl ester, and then reacted with (2S) -3,4-dihydro-2,5,7,8-tetramethyl-2-[ (4R, 8R) -4,8,12-trimethyltridecyl] -2H-1-benzopyran-6-ol under mild conditions to form the target product. This approach can enhance the reactivity of carboxylic acids, and the reaction conditions are relatively mild, with few side reactions.

I don't know the price of "3 - Pyridinecarboxylic acid, (2S) -3,4 - dihydro - 2,5,7,8 - tetramethyl - 2 - [ (4R, 8R) -4,8,12 - trimethyltridecyl] -2H - 1 - benzopyran - 6 - yl ester" on the market. The name of this compound is long and complicated, and it is a product of fine chemistry. It may be used in specific fields such as pharmaceutical research and development and organic synthesis.
The price on the market is often affected by many factors. One is the difficulty of preparation. If there are many synthesis steps, rare raw materials are required, and harsh reaction conditions are required, the cost will be high and the price will be expensive. The second is related to purity requirements. Those with high purity are used in high-end scientific research and pharmaceutical production, and the preparation is not easy and the price is high; those with lower purity are used in general experiments and industrial production auxiliary links, and the price may be slightly lower. Third, market supply and demand also have an impact. If the demand is strong and the supply is limited, merchants may raise prices; if the demand is weak and the supply is sufficient, the price will fall.
However, I have not checked the specific market information in detail, and it is difficult to say its exact price range. If you want to know the price of this compound, you can consult chemical reagent suppliers, chemical product trading platforms, or consult with relevant scientific research institutions and enterprises who are familiar with this, in order to obtain its more accurate price range.
