The synthesis method of 6,9-bis [ (2-aminoethyl) amino] anthrano [g] isoquinone-5,10-dione has been around for a long time. There are many methods and each has its own strengths. Today, this is the way for you.
First, it can be started by anthraquinones. Introduce the parent anthraquinone with an appropriate substituent, and gradually construct the structure of the target molecule through a multi-step reaction. For example, a halogen atom is introduced at a specific position of anthraquinone first, and then a nucleophilic substitution reaction occurs with an amino-containing reagent to introduce the (2-aminoethyl) amino moiety, followed by oxidation, cyclization and other steps to obtain the diaminoanthrano isoquinone. This process requires fine control of the reaction conditions, temperature, pH, etc. are all related to success or failure.
Second, the compound containing anthracycline is used as the raw material, and the heterosquare optical structure is constructed through photochemical reaction. Under the irradiation of light of a specific wavelength, the molecules undergo reactions such as rearrangement and cyclization to form an anthracene and [g] heterosquare photoskeleton, and then amino groups are introduced, modified and oxidized, and finally the target product is synthesized. The photochemical reaction requires a high purity of the light source and the reaction system. If there is a little carelessness, the yield will be poor.
Third, the biomimetic synthesis strategy is adopted. The chemical reaction process in living organisms is simulated, and the reaction is mediated by enzymes or biological catalysts. This method is green and environmentally friendly, but it is difficult to screen and cultivate biocatalysts, and the reaction conditions are relatively harsh. It is necessary to accurately simulate the environment in the organism in order to proceed smoothly.
Although all methods have their own advantages and disadvantages, they are all important ways to synthesize this compound. The road of synthesis is like seeking secrets, and researchers need to study carefully in order to open up a good path and obtain pure products, which will contribute to the development of chemistry.

6,9-Bis [ (2-aminoethyl) amino] anthracene-5,10-dione, this substance has the following precautions in the use process:
First, it is necessary to pay attention to its chemical properties. Because its structure contains multiple amino groups and a specific anthracene structure, its chemical activity is relatively high. Amino groups are prone to react with some substances with active hydrogen receptors, such as acids. The meeting of the two may trigger acid-base neutralization reactions and change the original structure and properties of the substance. Therefore, it should be avoided to be co-stored or mixed with acidic substances.
Second, about its photostability. The characteristics of "heterophore" show that the substance is more sensitive to light. Photochemical reactions may be triggered under light, resulting in structural changes, performance damage, and even harmful by-products. Therefore, be sure to store in a dark environment, such as in a brown bottle and stored in a dark place, and minimize the time and intensity of light during use.
Third, toxicity and protection. Due to its complex chemical structure, although there is a lack of clear toxicity data, some substances similar to nitrogen-containing heterocyclic and polycyclic aromatic hydrocarbons have certain toxicity. When operating, protective measures should be taken, such as wearing suitable protective gloves to avoid direct contact with the skin, because it may be absorbed through the skin; wearing protective glasses to prevent it from entering the eyes. If it is accidentally touched, rinse with plenty of water and seek medical attention immediately. At the same time, the operation should be carried out in a well-ventilated environment or in a fume hood to prevent inhalation of its dust or volatiles, which could damage the respiratory tract.
