To prepare the carboxylic acid ester of 2,3-dihydro-1H-pyrrole [3,4-c] pyrrole, the following ancient method can be followed.
First take a suitable starting material, such as those containing pyrrole structure and having a modifiable check point. In ancient methods, natural extracts or intermediates available through multi-step reactions are often used as starting points. Depending on the characteristics of the raw material, if it has active functional groups, such as halogen atoms, hydroxyl groups, etc., nucleophilic substitution can be used. Taking the halogen atom as an example, choose a nucleophilic reagent, such as an alkoxide, in an appropriate solvent, such as an aprotic polar solvent, stir at controlled temperature, so that the nucleophilic reagent attacks the halogen atom and forms an ether bond or the like.
If the starting material needs to introduce a fragment containing a carboxyl group, the esterification reaction can be used. Carboxylic acid and alcohol are used as substrates, and an appropriate amount of catalyst, such as concentrated sulfuric acid or p-toluenesulfonic acid, is added to the heat reflux state to make the two condensate to form an ester group. When reacting, pay attention to the choice of solvent, which needs to have good solubility to the reactants and does not side-react with the reactants and products.
Or the core structure of pyrrole [3,4-c] pyrrole can be constructed by cyclization. Select a substrate with suitable carbon chains and functional groups, and under suitable reaction conditions, such as specific temperature, pressure and catalyst action, make intramolecular rings. This process may involve multi-step reactions such as nucleophilic addition and elimination, and it is very important to precisely control the conditions of each step of the reaction.
After the reaction is completed, the product may be mixed with impurities, and the method of separation and purification should be used. According to the physical and chemical properties of the product and the impurity, such as boiling point, solubility, polarity, etc., distillation, recrystallization, column chromatography, etc. can be selected to obtain pure 2,3-dihydro-1H-pyrrole [3,4-c] pyrrole carboxylic acid ester.

I think what you are asking is about the "price range of 2,3-dihydro-1H-indolo [3,4-c] indoleone anhydride in the market". However, it is difficult to determine the price of these substances. The price often varies due to various factors, and it cannot be generalized.
First, the purity of this substance is extremely critical. If the purity is extremely high, almost flawless, its price will be high; if it contains impurities and the purity is slightly lower, the price will drop.
Second, the state of market supply and demand also affects its price. If there are many people who are seeking, but there are few suppliers, the so-called rare is expensive, and the price is self-increasing; on the contrary, if the supply is abundant and the demand is flat, the price may stabilize or even decline.
Third, the difficulty of preparation is also related to the price. If the preparation method is complicated, requires a lot of rare raw materials, or is time-consuming and labor-intensive, the cost will be high, and the price will rise accordingly; if the preparation is easier, the price may be relatively easy.
As far as I know, the price of this substance in the market ranges from tens to hundreds of dollars per gram. However, this is only an approximate number, and the actual price needs to be consulted with the chemical supplier in detail, or studied in the relevant trading market in order to be accurate. If the market situation is volatile, the price will also change accordingly, and it cannot be limited to one word.

2% 2C3-dihydro-1H-indolo [3,4-c] indolone, this is a delicate chemical substance, and its storage conditions need to be treated with caution.
Looking at the properties of this substance, it should be stored in a cool place. Due to high temperature, it is easy to cause its chemical structure to change, or cause adverse reactions such as decomposition. For example, on a hot summer day, direct sunlight and extreme heat in the environment can damage its chemical stability, so it should be avoided in the shade and the temperature should be constant in a suitable range to ensure its quality.
And it needs to be placed in a dry place. Moisture, like an invisible enemy, can quietly interact with the substance. Water molecules intervene, or loosen chemical bonds, changing its original properties. Just like a treasure in a humid land for a long time, it is easy to erode and lose its luster. The same is true of this salt, which may deteriorate when wet, and its effectiveness is greatly reduced.
Furthermore, sealed preservation is crucial. Many components in the air, such as oxygen and carbon dioxide, can interact with this substance. Oxygen or oxidation, carbon dioxide or participate in chemical reactions, sealing is like a strong barrier, blocking external interference and ensuring the purity and stability of the substance.
In summary, 2% 2C3-dihydro-1H-indolo [3,4-c] indolone salts, when stored in a cool, dry and sealed environment, can maintain their chemical stability for a long time, for subsequent scientific research, production and other purposes, without losing their effectiveness due to improper storage.
