3779-27-9 - Introduction
2,2 '-Bithienyl-5-carboxaldehyde is an organic compound with the chemical formula C10H8OS. The following is a description of its nature, use, preparation and safety information:
Nature:
2,2 '-Bithienyl-5-carboxaldehyde is a yellow to orange solid with a peculiar odor. It is stable at room temperature and soluble in common organic solvents such as ethanol and dichloromethane.
Use:
2,2 '-Bithienyl-5-carboxaldehyde is an important intermediate in organic synthesis. It can be used in the synthesis of organic materials, fluorescent dyes, photovoltaic materials and drugs. Its conjugated structure gives it good electronic conduction and optical properties, so it has a wide range of application potential in the field of optoelectronics.
Preparation Method:
2,2 '-Bithienyl-5-carboxaldehyde can be prepared by synthesis. A common synthetic method is the acylation of bithiophene and acetaldehyde. Specifically, the bithiophene is first reacted with an activating agent such as acetic acid or the like to form an activated bithiophene, which is then reacted with acetaldehyde under appropriate reaction conditions to form 2,2 '-Bithienyl-5-carboxaldehyde.
Safety Information:
2,2 '-Bithienyl-5-carboxaldehyde should be handled and stored to avoid contact with strong oxidants and strong acids. It can cause irritation and damage to the eyes, skin and respiratory tract. Therefore, appropriate personal protective equipment, such as gloves and glasses, should be worn during handling and handled in a well-ventilated area. If the skin or eyes are touched, rinse immediately with plenty of water and seek medical help. In addition, it also needs to be stored properly, away from fire and high temperature.
