High Quality 1,4-Dibromobenzene with CAS number 106-37-6 is a well - known organic compound. Its molecular formula is C₆H₄Br₂. The molecular weight is approximately 235.90 g/mol. This compound appears as a white to light - yellow crystalline solid at room temperature. It has a melting point in the range of 86 - 89°C and a boiling point around 219 - 220°C. It is sparingly soluble in water but soluble in many organic solvents such as ethanol, diethyl ether, and benzene. 1,4 - Dibromobenzene is also characterized by its relative stability under normal conditions, but it should be stored away from strong oxidizing agents and sources of ignition.
1,4 - Dibromobenzene finds wide application in the field of organic synthesis. It serves as a key intermediate in the production of various pharmaceuticals. For example, it can be used in the synthesis of certain anti - inflammatory drugs. In the realm of material science, it is used in the preparation of liquid - crystal polymers. The bromine atoms in the molecule can be substituted with other functional groups, enabling the creation of polymers with specific electrical and optical properties. Additionally, it is used in the production of dyes and pigments. The compound's structure allows it to participate in reactions that can produce colored compounds with good stability and color - fastness.
When handling High Quality 1,4 - Dibromobenzene, appropriate personal protective equipment (PPE) should be worn. This includes safety goggles, gloves, and a lab coat. The compound should be used in a well - ventilated area, preferably under a fume hood to avoid inhalation of any potentially harmful vapors. When measuring or transferring the product, use clean and dry glassware. If a solution is to be prepared, dissolve the compound in a suitable organic solvent slowly while stirring gently. For reactions involving 1,4 - Dibromobenzene, follow the reaction conditions specified in relevant literature carefully, including temperature, reaction time, and the use of catalysts.
Caso de síntese farmacêutica: A research group was working on the synthesis of a new anti - cancer drug. They used 1,4 - Dibromobenzene as a starting material. First, they carried out a substitution reaction where the bromine atoms were replaced with specific amine groups. The reaction was carried out in an ethanol solution at a temperature of 70°C for 4 hours with the presence of a palladium catalyst. After purification steps, they were able to obtain an intermediate compound with a high yield. This intermediate was then further reacted to form the final anti - cancer drug, which showed promising results in initial in - vitro tests.
Liquid - Crystal Polymer Case: A materials science team aimed to develop a new type of liquid - crystal polymer with improved electrical conductivity. They used 1,4 - Dibromobenzene to react with a diol compound. The reaction was carried out in a high - boiling - point organic solvent at 150°C for 8 hours. Through careful control of the reaction conditions, they were able to synthesize a polymer with a well - ordered structure. The resulting liquid - crystal polymer exhibited excellent electrical conductivity, which has potential applications in the field of electronic devices.
