What should be paid attention to when storing disodium 6- (5-chloro-2-hydroxy-4-sulfobenzene) -5-hydroxy-1-naphthalenesulfonate?
6 - (5 - cyano - 2 - fluoro - 4 - carboxybenzaldehyde) - 5 - fluoro - 1 - naphthalenesulfonic acid disodium salt should pay attention to the following matters when storing:
First, pay attention to the temperature and humidity of the storage environment. This compound is quite sensitive to temperature and humidity, and high temperature can easily cause changes in its chemical structure, which in turn affects its quality and performance. The temperature should be controlled within a specific range, usually at a low temperature and dry place, such as between 5 ° C and 25 ° C, and the relative humidity should be lower than 60%, which can effectively slow down its possible decomposition or deterioration.
Second, avoid coexistence with oxidizing and reducing substances. Due to its chemical properties, if it comes into contact with strong oxidizing agents or strong reducing agents, it is very likely to cause violent chemical reactions, or cause serious consequences such as combustion and explosion. Therefore, when storing, it is necessary to ensure strict isolation from such substances, and it is best to store in separate warehouses.
Third, pay attention to the material selection of the storage container. Materials with stable chemical properties and no reaction with them should be selected, such as glass, specific plastics, etc. Glass containers usually provide good chemical stability, which can effectively prevent the adsorption or chemical reaction of compounds with the container wall; if using plastic containers, it is necessary to ensure that the plastics do not interact with the compounds, so as not to contaminate the compounds or cause damage to the container.
Fourth, the storage place needs to have good ventilation conditions. Even if the compound is stored properly, it may accumulate in the local space due to trace volatilization. Good ventilation can disperse these volatile substances in time, reduce the concentration in the air, avoid the formation of a potentially dangerous environment, and also help to maintain the dry storage environment.
Fifth, do a good job of labeling and recording. Clearly label the name, specification, batch, storage date and other key information of the compound for easy management and traceability. At the same time, record the temperature and humidity changes during storage, inspection conditions, etc. If there is any abnormality, it can be detected in time and take corresponding measures.

At the same time, adding an appropriate amount of catalyst, the catalyst should be able to efficiently promote the reaction process without introducing too many impurities. Common catalysts or organic bases, the amount of which needs to be strictly controlled to prevent excessive catalysis from causing side reactions.
During the reaction process, closely monitor the reaction temperature and reaction time. The appropriate temperature range or within a certain range, such as 20 ° C - 50 ° C, needs to be precisely adjusted according to the specific reaction characteristics. The reaction time also needs to be accurately mastered. If it is too short, the reaction will be incomplete, and if it is too long, it is easy to exacerbate the side During this period, with the help of analytical methods such as thin-layer chromatography, the reaction process is monitored in real time, and the change of the raw material point is observed until the raw material point basically disappears and the product point reaches the expected state.
After the reaction is completed, the post-treatment operation is carried out. Usually, the reaction liquid is poured into an appropriate amount of water, and the difference in solubility between different substances in water and organic solvents is used for extraction and separation. The organic phase is collected, and the moisture is removed with a desiccant such as anhydrous sodium sulfate, and then distilled under reduced pressure to remove the organic solvent and obtain the crude product.
For further purification of the crude product, means such as column chromatography can be used. Select the appropriate silica gel column, with a specific proportion of eluent for elution, according to the product and impurities on the silica gel column adsorption and elution capacity of different, to achieve separation and purification, the final purity of 6 - (5 - cyano- 2 - methoxy - 4 - nitrobenzaldehyde) - 5 - methoxy - 1 - indenocarboxylate diethyl ester.
