To prepare 2,3-diacid, 5-isopropyl-diisopropyl ether, the method is as follows:
First take the appropriate starting material, depending on its structure, you can choose the corresponding carbon frame and functional group. If you start with a common organic compound, such as a hydrocarbon or a compound containing a specific substituent.
First apply a specific reaction to introduce a carboxyl group. It can be achieved by oxidation reaction, such as with a strong oxidant, under suitable reaction conditions, the carbon-hydrogen bond in the specific position of the raw material molecule is converted into a carboxyl group. This process requires careful adjustment of the reaction temperature, time and the amount of oxidant to prevent over-oxidation from impurities or low yields of the product.
For the introduction of isopropyl, a nucleophilic substitution reaction can be used. Reagents containing halogenated hydrocarbons, such as isopropyl halide, are reacted with nucleophilic raw materials. During the reaction, choose a suitable solvent and base to promote the nucleophilic substitution to proceed smoothly, so that the isopropyl group is connected to the target position.
Synthesis of diisopropyl ether, which can be obtained by dehydration reaction with isopropyl alcohol as raw material. Dehydrating agents such as concentrated sulfuric acid are commonly used to control the temperature to dehydrate the intermolecular isopropyl alcohol into ether. This reaction also needs to be controlled by temperature to avoid side reactions such as elimination reaction.
In the entire synthesis process, after each step of the reaction, it is necessary to make good use of separation and purification methods, such as distillation, recrystallization, column chromatography, etc., to obtain high-purity intermediate products and final target products. And each step of the reaction must be strictly monitored, and according to the reaction process and product analysis, the reaction conditions should be adjusted in time to achieve the best synthesis effect.

I look at what you said about "2,3-diacid, 5-ethyl-, diethyl ester", which is the name of the chemical substance. However, it is not easy to know its market price. Because the price is often affected by many factors.
First, the difficulty of obtaining raw materials and the fluctuation of prices have a great impact on the price of finished products. If raw materials are scarce and difficult to purchase, the price will be high. Second, the complexity and simplicity of the preparation process is also the key. If the process is complicated, many steps and special conditions are required, and manpower, material and financial resources are expended, the price will rise. Third, the balance between market demand and supply also affects the price. If the demand is strong and the supply is insufficient, the price will be high; conversely, if the supply exceeds the demand, the price will be low. Fourth, different manufacturers have different pricing due to different technologies and cost control.
In addition, geographical factors cannot be ignored. In different places, prices may vary due to different transportation costs and market environments. And market conditions are changing rapidly, and prices also fluctuate. Therefore, in order to determine its accurate market price, it is necessary to check the chemical product trading platform, consult the industry merchants, or refer to recent market survey reports to obtain more accurate price information.

2% 2C3-diacid, 5-isopropyl-diisopropyl ether, and diisopropyl ether need to pay attention to many key matters during storage and transportation.
This ether substance is flammable, and it is easy to burn and explode in case of open flames and hot topics. When storing, it must be stored in a cool and ventilated warehouse, away from fire and heat sources. The storage temperature should not exceed 30 ° C. It should be stored separately from oxidants and acids, and should not be mixed. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
When transporting, the transport vehicle should be equipped with the corresponding variety and quantity of fire equipment and leakage emergency treatment equipment. It is best to transport in the morning and evening in summer. The trough (tank) car used during transportation should have a grounding chain, and holes can be set in the trough to baffle to reduce shock and generate static electricity. It is strictly forbidden to mix with oxidants, acids, etc. During transportation, it should be protected from exposure to the sun, rain, and high temperature. Stopover should be kept away from fire, heat sources, and high temperature areas.
