For professionals in the chemical industry, a thorough understanding of a compound's properties and safe handling procedures is essential. 3-Methylbenzenethiol (CAS 108-40-7), also known as m-toluenethiol, is a significant chemical intermediate, and grasping its characteristics is key for successful and safe utilization. As a leading manufacturer and supplier, we provide insights into this important compound.

Physical and Chemical Properties:

3-Methylbenzenethiol is a liquid at room temperature, typically presenting as a clear, colorless to light yellow substance. Its distinct, often described as a potent or sensitive stench, is characteristic of thiols. Key physical properties include:

  • Molecular Formula: C7H8S
  • Molecular Weight: 124.2 g/mol
  • Boiling Point: Approximately 196 °C (lit.)
  • Melting Point: Below -20 °C
  • Density: Around 1.044 g/mL at 25 °C
  • Refractive Index: n20/D 1.5762 (lit.)
  • Flash Point: 163 °F (73 °C)
  • Acidity (pKa): 6.58 (at 25°C)

These properties highlight its nature as a reactive organic compound, suitable for a wide range of chemical transformations. Its relatively high boiling point means it is not highly volatile at standard room temperatures, yet its odor necessitates proper containment and ventilation.

Handling and Safety Precautions:

Given its potent odor and chemical reactivity, safe handling of 3-Methylbenzenethiol is paramount. As a responsible chemical supplier, we advise adhering to the following precautions:

  • Ventilation: Always use in a well-ventilated area or fume hood to minimize exposure to its strong odor and potential vapors.
  • Personal Protective Equipment (PPE): Wear appropriate chemical-resistant gloves (e.g., nitrile, neoprene), safety goggles or face shield, and protective clothing to prevent skin and eye contact.
  • Storage: Store in tightly sealed containers in a cool, dry, and well-ventilated place, away from incompatible materials such as strong oxidizers and bases. Keep away from heat, sparks, and open flames.
  • Inhalation: Avoid breathing vapors or mists. If inhaled, move the exposed person to fresh air and seek medical attention if symptoms persist.
  • Spills: In case of spills, contain the material and absorb with an inert material like sand or vermiculite. Dispose of in accordance with local regulations.

Our commitment as a manufacturer extends to providing comprehensive Safety Data Sheets (SDS) for 3-Methylbenzenethiol, which contain detailed information on hazards, handling, storage, and emergency procedures. We encourage all users to review the SDS thoroughly before working with the product.
