In the intricate world of chemical manufacturing, a thorough understanding of the raw materials used is fundamental to operational success and safety. 1,2,4-Trimethylbenzene, commonly known as pseudo-cumene, is one such chemical intermediate that requires careful consideration of its properties and handling protocols. As a key component in various industrial syntheses, from pharmaceuticals to dyes, knowing its characteristics is vital for researchers, formulators, and procurement managers. If you are looking to buy 1,2,4-Trimethylbenzene, familiarizing yourself with its profile is the first step.

Physical and Chemical Properties of 1,2,4-Trimethylbenzene

1,2,4-Trimethylbenzene (Molecular Formula: C9H12, Molecular Weight: 120.19 g/mol) presents itself as a colorless transparent liquid. Its physical characteristics are important for handling and storage:

  • Appearance: Colorless transparent liquid.
  • Boiling Point: Approximately 168 °C (lit.), indicating moderate volatility.
  • Melting Point: Recorded at -44 °C, meaning it remains liquid under most ambient conditions.
  • Flash Point: Around 120 °F (approximately 48.9 °C), classifying it as a flammable liquid. This necessitates careful handling to avoid ignition sources.
  • Refractive Index: n20/D 1.504 (lit.), a useful parameter for quality control and identification.
  • Density: Approximately 0.88 g/mL, influencing its behavior in mixtures and formulations.

Stability and Incompatibilities

Understanding the stability of 1,2,4-Trimethylbenzene is crucial for safe storage and use. It is generally stable but is incompatible with strong oxidizing agents, which can lead to vigorous reactions. Like many organic solvents, it may form explosive mixtures with air, especially when heated or atomized. Therefore, proper ventilation and avoidance of open flames or sparks are essential when working with this compound.

Recommended Storage and Handling Practices

For manufacturers and researchers looking to purchase 1,2,4-Trimethylbenzene, adhering to recommended storage and handling guidelines is paramount:

  • Storage Conditions: Keep containers tightly sealed in a cool, well-ventilated area, away from direct sunlight, heat sources, and ignition sources. It should be stored separately from oxidizing agents. Light loading and unloading practices are advised.
  • Handling: Personnel should be trained in the safe handling of flammable and potentially hazardous chemicals. Use appropriate personal protective equipment (PPE), including gloves, eye protection, and respiratory protection if ventilation is inadequate. Ensure eyewash stations and safety showers are readily accessible.
  • Transportation: Due to its flammability, proper transportation regulations must be followed, including appropriate labeling and packaging.

Sourcing Quality 1,2,4-Trimethylbenzene

When you choose to buy 1,2,4-Trimethylbenzene, selecting a reputable supplier is key. Look for manufacturers and distributors that provide comprehensive Safety Data Sheets (SDS) and Certificates of Analysis (CoA). These documents detail the product's physical and chemical properties, hazard information, and purity specifications, ensuring you receive a material that meets your application requirements and can be handled safely.
