2,1,3-苯并噻二唑-4-甲醛 - Introduction
2,1, is a compound containing benzothiadiazole and formaldehyde groups. Its chemical formula is C9H5N3OS and its molecular weight is 207.22g/mol.
Some of its main properties include:
1. appearance: powder or crystalline solid.
2. Solubility: Soluble in organic solvents such as chloroform, ethanol and dimethyl sulfoxide, slightly soluble in water.
3. Melting point: about 170-175°C.
2,1, has a wide range of applications in organic synthesis:
1. As a fluorescent material: Its derivatives can be applied to organic electronic devices, such as organic light-emitting diodes (OLED) and solar cells.
2. As an intermediate: It can be used as a starting material for the synthesis of other organic compounds, such as drugs and dyes.
The common method for preparing 2,1, benzothiadiazole is obtained by reacting the thiourea derivative of benzothiadiazole with formaldehyde. First, the thiourea derivative of benzothiadiazole is reacted with an oxidative aldehyde or acid anhydride to form an aldehyde intermediate, which is then treated with a base or directly hydrolyzed to obtain the target product.
Regarding safety information, 2,1, you need to pay attention to the following matters during use and handling:
1. should avoid contact with skin and eyes, such as accidental contact, should immediately rinse with plenty of water and seek medical help.
2. in the use of the process should maintain good ventilation conditions, to prevent inhalation of vapor or dust.
3. Store it in a sealed container, away from fire and oxidant.
4. Wear appropriate personal protective equipment such as goggles, gloves and protective clothing during handling.
It is best to use and handle 2,1, and 2 correctly under the guidance of professionals.
