The product we are introducing here is Factory Supply 1-Bromonaphthalene with the CAS number 90 - 11 - 9. It is offered at a low price, which makes it an attractive option for various industries. 1-Bromonaphthalene is a colorless to yellowish liquid. It has a molecular formula of C₁₀H₇Br and a molecular weight of approximately 207.07 g/mol. The boiling point of 1-Bromonaphthalene is around 281 - 282 °C, and its density is about 1.48 g/cm³ at 25 °C. It is insoluble in water but soluble in many organic solvents such as ethanol, ether, and benzene.
1-Bromonaphthalene has a wide range of applications in different fields. In the field of organic synthesis, it serves as an important intermediate. It can be used in the preparation of various naphthalene derivatives. For example, through a series of chemical reactions, it can be converted into naphthol derivatives, which have applications in the production of dyes and pigments. In the field of material science, 1-Bromonaphthalene can be used in the modification of polymers. It can react with some polymer chains to improve the performance of the polymers, such as enhancing their thermal stability and mechanical strength. In addition, it can also be used in the research of liquid crystals. Some liquid crystal compounds can be synthesized using 1-Bromonaphthalene as a starting material, which are widely used in display devices.
When using 1-Bromonaphthalene, it is necessary to follow strict safety procedures. First of all, it should be handled in a well - ventilated area or under a fume hood to avoid inhalation of its vapors. Wear appropriate personal protective equipment, including safety glasses, gloves, and a lab coat. During the handling process, avoid contact with skin and eyes. If contact occurs, immediately rinse with plenty of water for at least 15 minutes and seek medical attention. In terms of storage, it should be stored in a cool, dry place away from sources of ignition and oxidizing agents. When using it for chemical reactions, carefully follow the reaction conditions and procedures. For example, in a reaction with other reagents, pay attention to the reaction temperature, time, and the stoichiometry of the reactants.
Case 1: Organic Synthesis of Naphthol Derivatives
In a laboratory setting, a chemist wants to synthesize a particular naphthol derivative. First, dissolve 1-Bromonaphthalene in anhydrous ether in a round - bottom flask. Then, add a specific Grignard reagent drop - by - drop under a nitrogen atmosphere. After the addition is complete, reflux the reaction mixture for several hours. Next, hydrolyze the reaction product with dilute hydrochloric acid. Through a series of purification steps such as extraction, distillation, and recrystallization, the desired naphthol derivative can be obtained. This derivative can be further used in the production of high - quality dyes.
Caso 2: Modificação de polímeros
A polymer scientist wants to improve the thermal stability of a certain polymer. Dissolve 1-Bromonaphthalene and the polymer in a common solvent in a reaction vessel. Then, add a catalyst and heat the mixture under controlled conditions. The 1-Bromonaphthalene reacts with the active sites on the polymer chains. After the reaction is completed, the modified polymer is precipitated by adding a non - solvent. The resulting polymer shows enhanced thermal stability, which can be used in applications where high - temperature resistance is required, such as in the automotive and aerospace industries.
