In the chemical industry, understanding the detailed profile of a compound is crucial for its safe and effective application. 9-Bromo-10-phenylanthracene (CAS 23674-20-6) is a specialized organic intermediate with a unique set of properties that make it valuable, particularly in the field of organic electronics. This article outlines its key chemical and physical characteristics, along with essential handling and storage advice for industrial users.

Physical and Chemical Characteristics

9-Bromo-10-phenylanthracene is typically supplied as a slightly yellow powder. This physical form is common for many polycyclic aromatic compounds and is generally easy to handle in laboratory and industrial settings. Key properties include:

• Molecular Formula: C20H13Br
• Molecular Weight: Approximately 333.22 g/mol
• Melting Point: Typically in the range of 154-155°C. This relatively high melting point indicates that the compound is stable as a solid at ambient temperatures.
• Boiling Point: Around 449.7°C. This high boiling point suggests good thermal stability, important for processes that might involve elevated temperatures.
• Density: Approximately 1.393 g/cm³.
• Solubility: It is generally insoluble in water but soluble in certain organic solvents, particularly hot non-polar solvents, and polar solvents like dimethylformamide (DMF) and dimethyl sulfoxide (DMSO). This solubility profile influences its use in various reaction media and purification processes.
• Purity: Commercial grades often boast high purity, typically ≥99.0% (by HPLC or GC), with low moisture content (≤0.5%) and controlled total impurities (≤1.0%). This high purity is critical for its application in sensitive electronic devices.

Safety and Handling Precautions

While specific hazard classifications may vary by supplier, compounds of this nature can be irritants. Common GHS hazard statements may include H302 (Harmful if swallowed), H315 (Causes skin irritation), H317 (May cause an allergic skin reaction), H319 (Causes serious eye irritation), and H335 (May cause respiratory irritation). Therefore, appropriate safety measures must be observed when handling:

• Personal Protective Equipment (PPE): Always wear suitable gloves (e.g., nitrile), safety goggles, and a lab coat. In situations where dust may be generated, respiratory protection should be used.
• Ventilation: Handle the material in a well-ventilated area, preferably under a fume hood, to minimize inhalation exposure.
• Storage: Store in a cool, dry, well-ventilated place, keeping the container tightly closed. Avoid exposure to incompatible materials, such as strong oxidizing agents.
• Spill Management: In case of spills, contain the material, avoid generating dust, and clean up using appropriate absorbent materials, disposing of them according to local regulations.

Sourcing and Usage Advice
