Product Introduction: β - Bromobenzene appears as a transparent colorless to pale yellow liquid. It is a fine chemical product with a wide range of applications, mainly used as a key raw material for electronic resins in 5G and 6G new materials. It synthesizes high-efficiency brominated flame retardant material polybrominated styrene, which can be used as a new flocculant and dispersant in industry. It is also an excellent fiber dyeing modifier, anti-static agent for plastics, fibers and paper, viscosity regulator in photosensitive material production, ion exchange resin and exchange membrane, electroplating gloss agent, etc. The application areas and market value of β - bromophenethyl in the pharmaceutical field. Drug synthesis intermediates: used for the synthesis of key intermediates for the anti asthma drug Prenzostat (such as 4- (4-phenylbutoxy) benzoic acid). Prenzostat, as a leukotriene receptor antagonist, has significant therapeutic effects on various types of asthma and allergic rhinitis. ·Other drugs: Participate in the synthesis of insecticides, antihypertensive agents, and other pharmaceutical products. Industrial field · Flame retardant intermediate: Synthesis of high-efficiency brominated flame retardant polybrominated styrene. ·Functional materials: used as coagulants, dispersants, fiber dyeing modifiers, antistatic agents, viscosity regulators for photosensitive materials, and electroplating gloss agents.
