For chemical engineers, research scientists, and procurement professionals, a thorough understanding of a chemical's properties is fundamental to its safe and effective use in industrial settings. 3-Bromo-4-chlorotoluene (CAS 57310-39-1) is a key intermediate in organic synthesis, and its physical and chemical characteristics dictate its handling, storage, and application suitability.

Key Physical and Chemical Characteristics

3-Bromo-4-chlorotoluene is identified as a colorless transparent liquid. Its molecular formula is C7H6BrCl, with a molecular weight of approximately 205.480. Understanding its properties provides critical insights for industrial applications:

• Density: Approximately 1.5±0.1 g/cm³. This density indicates it is heavier than water, which is relevant for phase separations and storage considerations.
• Boiling Point: Recorded at 229.1±20.0 °C at 760 mmHg. This relatively high boiling point suggests that the compound is stable under moderate heating conditions and does not readily volatilize at ambient temperatures.
• Flash Point: Approximately 104.5±11.9 °C. This parameter is crucial for fire safety. A flash point above 100°C generally classifies it as a combustible liquid rather than a highly flammable one, requiring standard safety precautions against ignition sources.
• Vapour Pressure: Low, around 0.1±0.4 mmHg at 25°C. This low vapor pressure minimizes the risk of significant vapor concentration in the air during handling, reducing inhalation hazards, though proper ventilation remains essential.
• Index of Refraction: 1.566. This optical property can be useful for identification and quality control purposes.
• Purity: Typically specified as ≥98.0%. This high purity is critical for its role as an intermediate, ensuring minimal interference in complex synthetic processes.

Safe Handling and Storage Recommendations

Based on these properties, 3-Bromo-4-chlorotoluene should be stored in a cool, well-ventilated place, in a tightly sealed container. While its low vapor pressure and high flash point contribute to safer handling, it's important to avoid contact with skin and eyes and to use appropriate personal protective equipment (PPE) such as gloves and safety glasses. As with all organic chemicals, avoiding ignition sources and ensuring adequate ventilation are standard safety practices.
