thianaphthene-3-carboxaldehyde - Introduction
thianaphthene-3-carboxaldehyde(thianaphthene-3-carboxaldehyde) is an organic compound whose molecular formula is C12H8OS, and its structure contains benzothiophene and formyl groups.
The nature of the thianaphthene-3-carboxaldehyde is as follows:
-Appearance: Colorless to light yellow solid
-Solubility: Soluble in organic solvents such as chloroform, dimethylformamide and dichloromethane
-Melting point: about 125-130 degrees Celsius
-Stability: relatively stable at room temperature
Application of thianaphthene-3-carboxaldehyde:
-As an intermediate in organic synthesis, it can be used to synthesize biologically active compounds, such as drugs, dyes and photosensitive compounds.
-Used in the construction of organic light-emitting diodes (OLED) and other devices to improve their performance.
Preparation of thianaphthene-3-carboxaldehyde:
It is usually prepared by reacting benzothiophene with a formylation reagent. For example, benzothiophene is dissolved in methylene chloride, an appropriate amount of methyl anhydride and a base catalyst are added, the reaction is stirred at room temperature for several hours, and the target product is obtained through the steps of separation, washing, concentration and crystallization.
