1040281-97-7 - Introduction

3-Chlorothiophene-2-boronic acid pinacol ester is a compound whose chemical formula is C12H8BClO2S. The following is a description of its nature, use, preparation and safety information:

Nature:
3-Chlorothiophene-2-boronic acid pinacol ester is a solid material with white or light yellow crystals. It has good solubility, can be dissolved in solvents, and decomposed in water. The compound is a photosensitive compound that can undergo a specific chemical reaction under the irradiation of ultraviolet light or visible light.

Use:
3-Chlorothiophene-2-boronic acid pinacol ester is widely used in the field of optoelectronics, especially in the manufacturing process of organic light-emitting diodes (OLED). As a material for the light-emitting layer, it can emit light of different colors and is used in the manufacture of electronic products such as color displays and flat-panel TVs.

Preparation Method:
A common method for preparing 3-chlorothiophene-2-boronic acid pinacol ester is through chemical synthesis. First, 3-chlorothiophene-2-boronic acid is reacted with pinacol to produce a derivative having an alcohol group. Then, using an appropriate acid or base catalyst, the derivative is esterified to produce the target compound.

Safety Information:
3-chlorothiophene-2-boronic acid pinacol ester has good stability under normal circumstances, but it can be used as a photosensitive compound, so long exposure to strong light should be avoided. In addition, although the compound is relatively stable at room temperature, it will cause combustion reaction under the action of high temperature, flame or open flame. Therefore, it is necessary to pay attention to fire prevention measures during handling or use, and to store in a dry and ventilated place to avoid contact with flammable substances. Any laboratory personnel using the compound should be familiar with its safe operating procedures and wear appropriate personal protective equipment. If an accident occurs, appropriate emergency measures must be taken immediately.
