Dibutyl thiodiglycolate (Thiodiglycolic acid dibutyl ester) is an organosulfur compound primarily used as a plasticizer and stabilizer in polymer formulations. With a density of 1.059 g/cm³ and boiling point of 329.5±27.0°C at 760 mmHg, it features characteristic ester and thioether functional groups. The compound shows limited water solubility but is miscible with common organic solvents. Storage should be in airtight containers protected from light and moisture at room temperature. Safety precautions include wearing chemical-resistant gloves and eye protection due to potential skin/eye irritation (GHS Category 2). Its molecular structure enables applications in specialty polymer synthesis and as a sulfur-containing building block in organic transformations.
