Overview
Dibenzopyrene is a brominated derivative of pyrene, a polycyclic aromatic hydrocarbon (PAH). It is primarily used in research and industrial applications due to its unique chemical properties. The compound is known for its stability and aromatic structure, making it valuable in organic synthesis and material science. Dibenzopyrene is typically synthesized through bromination of pyrene, resulting in a compound that retains the aromatic characteristics of pyrene while introducing bromine atoms that enhance its reactivity and utility in further chemical reactions.
Physical and Chemical Properties
Dibenzopyrene appears as a yellow to brown crystalline powder with a molecular weight of 360.04 g/mol. It is soluble in organic solvents such as dichloromethane and toluene but is insoluble in water. The compound has a melting point range of approximately 180-200°C, which is typical for brominated aromatic compounds. Key chemical properties include its high stability and aromaticity, which make it useful in various chemical reactions. The presence of bromine atoms also allows for further functionalization, making dibenzopyrene a versatile intermediate in organic synthesis.
Main Applications
Dibenzopyrene is primarily used in research laboratories and industrial settings. Its applications include serving as a building block in the synthesis of more complex organic compounds, particularly in material science where aromatic hydrocarbons are valued for their electronic properties. In addition, dibenzopyrene is used in the development of organic semiconductors and other advanced materials. Its brominated structure allows for further modification, enabling researchers to tailor its properties for specific applications.
Safety and Storage
Due to its potential hazards, dibenzopyrene should be handled with care. It may be harmful if inhaled or ingested, and appropriate personal protective equipment (PPE) such as gloves and goggles should be used. The compound should be stored in a cool, dry place away from light and oxidizing agents to maintain its stability. Proper disposal methods should be followed to prevent environmental contamination. Safety data sheets (SDS) provided by the supplier should be consulted for detailed handling and storage instructions.
B2B Procurement Guide
When procuring dibenzopyrene, buyers should prioritize suppliers who provide detailed purity and safety data. The reference price range is approximately $200-$500 per gram, depending on purity and supplier. Bulk orders may offer cost savings, so buyers should negotiate with suppliers for larger quantities. It is also advisable to verify the supplier's reputation and compliance with regulatory standards. Ensuring proper documentation and testing for purity can help avoid issues in downstream applications.
