For professionals working with specialized chemicals, a thorough understanding of product properties and safe handling procedures is paramount. 3,4-Dimethoxythiophene (DMOT), CAS 51792-34-8, is a versatile intermediate used across various industries, from organic electronics to pharmaceuticals. As a trusted manufacturer and supplier, we aim to provide comprehensive information to ensure its effective and safe use.

Key Properties of 3,4-Dimethoxythiophene

DMOT is typically described as a light yellow to colorless liquid or solid, depending on ambient temperature (melting point is around 23°C). Its molecular formula is C6H8O2S, with a molecular weight of 144.19 g/mol. Key physical and chemical properties include:

  • Appearance: Colorless to light yellow liquid or solid.
  • Boiling Point: 100-102 °C at 10-11 mmHg.
  • Density: Approximately 1.209 g/mL at 25 °C.
  • Refractive Index: Around 1.5409.
  • Solubility: Miscible with most common organic solvents, but only slightly miscible with water.
  • Flash Point: 224 °F (106 °C).
  • Purity: Typically available at ≥ 98% or ≥ 99% purity.

These properties dictate its handling and storage requirements. The relatively low boiling point under vacuum and miscibility with organic solvents make it amenable to various chemical reactions and purification techniques.

Safety and Handling Precautions

While DMOT is a valuable chemical intermediate, like all chemicals, it requires careful handling. Based on available safety data (SDS), users should be aware of:

  • Irritation: It can cause skin and serious eye irritation (H315, H319).
  • Inhalation: May cause respiratory irritation (H335).
  • Ingestion: Harmful if swallowed (H302).
  • Handling: Always use appropriate personal protective equipment (PPE), including gloves, safety goggles, and lab coats. Ensure adequate ventilation, preferably in a fume hood.
  • Storage: Store in a tightly closed container in a cool, dry, and well-ventilated area, away from incompatible materials and sources of ignition. Recommended storage temperature is typically ≤ -20 °C.

For detailed safety information, always refer to the latest Safety Data Sheet (SDS) provided by the supplier.
