This article delves into its fundamental chemical properties, recommended handling practices, and its key industrial applications, offering insights for procurement and technical teams.

Key Chemical Properties of 3-Methoxybenzenethiol

3-Methoxybenzenethiol, known chemically as 3-methoxythiophenol or 3-mercaptoanisole, is characterized by its clear, colorless to light yellow liquid appearance. Its molecular formula is C7H8OS, with a molecular weight of approximately 140.203 g/mol. Key physical and chemical properties include:

  • Boiling Point: Typically around 223-226 °C (lit.), indicating a relatively low volatility under standard conditions.
  • Flash Point: Reported as 96 °C, signifying that it is a combustible liquid and requires appropriate fire safety precautions.
  • Density: Approximately 1.13 g/mL at 25 °C.
  • Solubility: It is not readily miscible with water but is soluble in common organic solvents like methanol, benzene, hexane, toluene, and dichloromethane.
  • Reactivity: The thiol (-SH) group is the primary reactive site, readily undergoing oxidation to disulfides, alkylation to form thioethers, and participating in nucleophilic substitution reactions.
  • Odor: Characteristically possesses a strong, unpleasant odor (stench), necessitating handling in well-ventilated areas or under fume hoods.

Understanding these properties is vital for its effective use as an intermediate and for ensuring safe storage and handling.

Safe Handling and Storage Recommendations

Due to its characteristic stench and combustible nature, proper handling of 3-Methoxybenzenethiol (CAS 15570-12-4) is essential:

  • Ventilation: Always handle in a well-ventilated area or under a fume hood to manage the odor and potential inhalation hazards.
  • Personal Protective Equipment (PPE): Wear appropriate gloves (e.g., nitrile or neoprene), safety goggles, and protective clothing to prevent skin and eye contact.
  • Ignition Sources: Keep away from heat, sparks, open flames, and other ignition sources, given its flash point.
  • Storage: Store in a tightly closed container in a cool, dry, and well-ventilated place, ideally at refrigerated temperatures (2-8 °C) as per supplier recommendations, to maintain its stability and quality.

Procurement managers should always consult the Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) for detailed safety information before purchasing or handling this chemical.
