Pyridine, 2-(2-thienyl)- - Introduction
2-(2-thienyl) pyriridine (2-(2-thienyl) pyriridine) is an organic compound with the chemical formula C9H7NS. The following is a description of its nature, use, formulation and safety information:
Nature:
-Appearance: 2-(2-thienyl)pyridine is a colorless to yellow crystal or powdery substance.
-Melting point: about 65-70 ℃.
-Solubility: The compound is soluble in common organic solvents such as dimethyl sulfoxide, methanol, chloroform and ethanol.
Use:
- 2-(2-thienyl)pyridine is widely used as an organic semiconductor and fluorescent dye in devices such as organic light-emitting diodes (OLED) and organic solar cells.
-The compound is also used as a synthetic intermediate for some fluorescent probes, biomarkers and anti-tumor drugs.
Method:
- 2-(2-thienyl)pyridine can be obtained by the reaction of 2-hydrazonopyridine and 2-thiophenyl borate. First, 2-hydrazonoylpyridine and a boronic acid ester are reacted under basic conditions to form a boronic acid hydrazone. Then, a solution of boronic acid hydrazone was obtained by funnel separation. Finally, 2-(2-thienyl)pyridine is generated by heating the boronic acid hydrazone solution in the presence of thiophenol.
Safety Information:
- 2-(2-thienyl)pyridine has no obvious toxicity to human body under normal use conditions.
-However, the compound may have irritating effects on the eyes, skin and respiratory tract. Pay attention to protective measures when exposed.
-Avoid inhaling its dust or vapor, and avoid contact with strong oxidants and strong acids.
-When using or handling the substance, wear suitable personal protective equipment, such as gloves and safety glasses, and ensure that the operation is carried out in a well-ventilated place. Always read and understand the relevant safety data sheets before any processing.
