To prepare this " (3Z) -3- [2- (5-chloro-2-phenoxyphenyl) hydrazine fork] -5- {[ (4-methylphenyl) sulfonyl] amino} -4-oxo-3,4-dihydronaphthalene-2,7-disulfonate disodium", the process is as follows:
First, the raw materials need to be prepared, 5-chloro-2-phenoxyaniline, 4-methylbenzenesulfonyl chloride, 2,7-naphthalene disulfonic acid, etc., all of which must be of high quality and quality.
Combine 5-chloro-2-phenoxy aniline with an appropriate amount of sodium nitrite and acid to form a solution, and carry out the diazotization reaction at low temperature. This step requires careful control of the temperature to prevent the decomposition of diazonium salts. After the diazotization, pour it slowly into the alkaline solution containing 2,7-naphthalene disulfonic acid, and the coupling reaction occurs. The reaction needs to be continuously stirred to make the two fully contact, and the pH value and temperature should be closely monitored to promote the smooth reaction.
To complete the coupling reaction, take 4-methylbenzenesulfonyl chloride and slowly add the above reaction solution. This step should also pay attention to the temperature to avoid overreaction. 4-Methylbenzenesulfonyl chloride is acylated with the amino group in the product to form the main structure of the target.
The reaction is final, and the product is extracted with an appropriate organic solvent to remove impurities and purify. Then it is distilled under reduced pressure to disperse the organic solvent to obtain a crude product. The crude product is dissolved in an appropriate amount of hot water, and an appropriate amount of precipitant is added dropwise to make the product crystallize and precipitate. The crystals are filtered, rinsed with cold water to remove impurities, and finally dried at low temperature to obtain a pure " (3Z) -3- [2- (5-chloro-2-phenoxyphenyl) hydrazidine] -5- {[ (4-phenylmethyl) sulfonyl] amino} -4-oxo-3,4-dihydronaphthalene-2,7-disodium disulfonate" product. The whole operation requires strict adherence to procedures in order to obtain high-quality products.

When using (3Z) -3- [2- (5-chloro-2-phenoxyphenyl) hydrazine fork] -5- {[ (4-methylphenyl) sulfonyl] amino} -4-oxo-3,4-dihydronaphthalene-2,7-disulfonate disodium products, pay attention to the following matters.
This substance may have specific chemical activities and latent risks. Its appearance and properties should be carefully observed to ensure that it meets the corresponding standards. If abnormal color, odor or morphological changes are seen, it needs to be handled with caution to prevent subsequent use effects or accidents.
Strict requirements must be followed when storing. It should be placed in a dry, cool and well-ventilated place, away from fire sources, heat sources and strong oxidants. Due to its chemical structure characteristics, improper storage or deterioration and decomposition may not only make the product ineffective, but may even cause dangerous reactions.
During operation, protective measures are essential. Appropriate protective equipment should be worn, such as protective gloves, goggles and masks. The substance may cause irritation to the skin, eyes and respiratory tract. If inadvertently contacted, rinse with plenty of water immediately and seek medical attention according to specific conditions.
When using, precise control of the dosage is extremely critical. According to the specific application and reaction requirements, it needs to be added in strict accordance with the specified dosage. Excessive or insufficient dosage may have a serious impact on the results.
At the same time, it is necessary to fully consider its compatibility with other substances. Before mixing, it should be rigorously tested to confirm that no adverse reactions will occur, such as precipitation, gas release or violent chemical reactions, so as not to endanger safety or damage the reaction system.
In addition, relevant operations should be carried out under the guidance of professionals or under the premise of professional knowledge. If there is any doubt about its nature and use method, it should consult a professional in time, and must not act blindly to ensure the safety of the use process and achieve the desired effect.
