Navigating the procurement of specialized chemical intermediates requires a keen understanding of product specifications. For professionals involved in advanced materials, particularly OLED technology and organic synthesis, 1-Bromo-3,5-diphenylbenzene (CAS: 103068-20-8) is a compound of significant interest. As a dedicated manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. aims to demystify these specifications, ensuring our clients can confidently buy the materials they need.

This guide focuses on the essential technical details of 1-Bromo-3,5-diphenylbenzene, helping you select the right product for your specific application. When you are ready to purchase, you'll know exactly what to look for in a supplier.

Key Identifiers and Purity Requirements

The first step in any chemical procurement is accurate identification. For 1-Bromo-3,5-diphenylbenzene, the CAS number 103068-20-8 is universally recognized. Its chemical name, 1-Bromo-3,5-diphenylbenzene, and common synonyms such as 5'-Bromo-1,1':3',1''-terphenyl are also important for cross-referencing. The molecular formula C18H13Br and molecular weight of 309.20 further confirm its identity.

However, the most critical specification for demanding applications like OLEDs is purity. Our 1-Bromo-3,5-diphenylbenzene is guaranteed to have an assay of ≥99.0%. This high level of purity is essential because impurities can act as quenchers or trap sites in organic electronic devices, severely impacting their performance and lifespan. For buyers, always request a Certificate of Analysis (COA) to verify the purity and confirm that it meets your project’s stringent requirements.

Physical and Chemical Properties: Practical Insights

Understanding the physical attributes of a chemical intermediate is vital for effective handling, storage, and integration into synthesis processes:

  • Appearance: 1-Bromo-3,5-diphenylbenzene is typically supplied as a white powder. Variations in color might indicate the presence of impurities, so consistency in appearance is a good sign of quality.
  • Melting Point: With a melting point usually in the range of 105-106°C, this characteristic is important for determining appropriate handling temperatures and for purification validation.
  • Boiling Point: The reported boiling point of approximately 401.1°C (with variations such as ±14.0°C) indicates its thermal stability under atmospheric pressure, though vacuum distillation is often preferred for such high-boiling compounds.
  • Density: A density of around 1.309 g/cm³ provides information relevant for volumetric calculations in process design.

Packaging, Storage, and Sourcing Considerations

Reliable suppliers will offer robust packaging solutions, such as 25 kg drums, to protect the chemical during transit and storage. Proper storage conditions, typically cool and dry environments, are crucial for maintaining the compound's integrity over time. When you are ready to buy 1-Bromo-3,5-diphenylbenzene, consider working with a manufacturer like NINGBO INNO PHARMCHEM CO.,LTD., which offers:
