To prepare 1,2-dichloro-4-oxo-cyclopentane-3-enocarboxylic acid, there are three methods.
First, cyclopentadiene is used as the starting point, and it can be obtained through diene addition, oxidation, halogenation, hydrolysis and other steps. First, cyclopentadiene is added to the diene body by diene addition reaction to obtain the corresponding adduct. This adduct can be oxidized at a specific location under suitable oxidation conditions, such as treatment with a specific oxidant. Then halogenated, chlorine atoms are introduced, and finally hydrolyzed to convert a specific group into a carboxyl group, thereby obtaining the target product.
Second, a specific cyclopentene-containing compound can be started. The compound is first modified by functional groups, so that a suitable substituent is introduced at a certain position on cyclopentene, and then the specific atom is oxidized to the desired valence state through the oxidation process to form an oxygen-containing structure. Then halogenation, chlorine atoms are introduced at a specific position precisely, and finally the carboxyl group is adjusted through suitable reaction conditions to obtain 1,2-dichloro-4-oxycyclopentane-3-enocarboxylic acid.
Third, other similar structures are used as raw materials. First, the ring is rearranged by ring opening or ring expansion to construct a suitable carbon frame. Then it is oxidized, halogenated and carboxylated in multiple steps. During oxidation, the conditions are strictly controlled to enable specific atoms to reach the desired oxidation state; during halogenation, the appropriate halogenating agent and conditions are selected to ensure the accurate introduction of chlorine atoms; the carboxylation step adjusts the reaction conditions so that the product finally forms the target carboxyl group structure, and then 1,2-dichloro-4-oxo-cyclopentane-3-enocarboxylic acid is obtained.

1% 2C2-dibromo-4-oxovaleric acid-3-enoic acid is in the market, and its price range is quite difficult to determine. The price often varies due to various reasons, such as the output of the place of origin, the supply and demand of the city, the production process, and the quality.
If its origin is wide and the output is abundant, and it is supplied in the market, but there are few people in need, the price may decline. On the contrary, if the origin is narrow, the output is thin, and there are many people in demand, the supply will exceed the demand, and the price will rise.
Furthermore, the complexity of the preparation process is also related to the price. If the process is complicated, expensive, time-consuming, and labor-intensive, the price will be higher; if it is simple, the price may be slightly lower.
As for the quality, the better one is expensive, and the second one is less expensive.
In summary, in order to determine the price range between markets, it is necessary to check the dynamics of the market in real time, consult suppliers and industry players, and obtain a more accurate number. However, according to common sense, the price of this compound may be between tens of yuan and hundreds of yuan per gram due to use, demand, etc., or there are more than one. It is difficult to generalize, and it all changes with the market.

1% 2C2-dicyanobicyclo [3.2.0] heptyl-3-enoic acid, this thing is highly toxic and dangerous, so its storage needs to be extremely cautious, according to ancient regulations, as follows.
The hiding place must be selected in a remote, quiet and inaccessible place, and it must be dry and ventilated to prevent moisture and corrosion. There should be no fireworks around, nor near flammable and explosive things. Because of its strong nature, it may cause a dramatic explosion in case of fire or hot topic, and it will affect the four sides.
The reservoir should be specially made of a sturdy container, and the material should be resistant to corrosion to prevent leakage. The words "highly toxic" should be written on the outside of the container, which is conspicuously displayed, so that everyone who sees it knows the danger.
The storage place should be guarded by a special person, and those who trespass should be severely punished. Those on duty must be familiar with the nature of this thing and always have measures to deal with it. If there is an accidental leakage, cover it with lime and sand as soon as possible, and do not touch it rashly. Urgent report to the company and deal with it quickly.
The temperature of storage should be constant and moderate, and it should not be suddenly cold and hot. In summer, it should be cooled by an ice cellar or water cooling method; in winter, it should be wrapped in felt cotton to prevent freezing.
In short, the storage of 1% 2C2-dicyano-4-oxobicyclo [3.2.0] heptyl-3-enoic acid is related to human life and safety, and the well-being of mountains and rivers. It is necessary to follow the ancient law and strictly implement it.
