For storage, it should be kept in a cool, dry place away from direct sunlight and sources of heat. When using it in a chemical reaction, add it slowly to the reaction mixture while stirring continuously. This helps to ensure a homogeneous reaction and prevent any potential side reactions. The reaction conditions, such as temperature, pressure, and reaction time, should be carefully controlled according to the specific reaction requirements.
Let's take the synthesis of a liquid - crystal material as an example. A research team was aiming to develop a new type of liquid - crystal compound with enhanced optical properties. They chose 4,4′-bis(chloromethyl)-1,1′-biphenyl as the starting material. First, they dissolved the compound in a suitable organic solvent, such as dichloromethane. Then, they added a specific amine compound under controlled temperature and stirring conditions. The reaction was allowed to proceed for several hours until the desired intermediate was formed. After purification steps, the intermediate was further reacted with other reagents to form the final liquid - crystal compound. The new liquid - crystal compound showed improved response time and contrast ratio compared to the existing materials. Through this case study, it is evident that the proper use of 4,4′-bis(chloromethyl)-1,1′-biphenyl can lead to the development of high - quality products.
