17630-76-1 - Introduction
5-Chloroisatin is an organic compound with the chemical formula C16H8Cl2N2O2. It is a red compound, commonly in the form of red needle crystals. The following is a description of the nature, use, preparation and safety information of 5-Chloroisatin:
Nature:
-Appearance: 5-Chloroisatin is a red needle-like crystal.
-Melting point: Melting point is about 297-299 ° C.
-Solubility: insoluble in water, but soluble in organic solvents such as alcohol, ether and dichloromethane.
Use:
-Biological research: 5-Chloroisatin is commonly used as a biological dye, such as the nucleus, cytoplasm and cell membrane stain.
-Culture and art: Due to its bright red color, 5-Chloroisatin is also used as an ingredient in dyes, pigments and inks.
Method:
- 5-Chloroisatin can be prepared by acetylation of cyanide 4,5-dichloro-diamino acid. First, 4,5-dichloro-diamino cyanide is reacted with acetic anhydride to form 4,5-dichloro-diaminoacetate cyanide. This intermediate is then reacted with cyanobromide to give cyano 4,5-dichloro-diaminoacetate. Finally, hydrogenation of this intermediate under basic conditions gives 5-Chloroisatin.
Safety Information:
- 5-Chloroisatin is non-toxic to humans. However, as a chemical substance, when it comes into contact with the skin or eyes, it should be rinsed immediately with plenty of water.
-During the operation of 5-Chloroisatin or its preparation, care should be taken to avoid inhaling its powder or solution to avoid irritation to the respiratory system.
-When storing or handling 5-Chloroisatin, avoid contact with oxidants, strong acids or strong bases to avoid dangerous reactions.
Please note that for the use or handling of chemicals, laboratory or professional guidance is recommended.
