Ethyl thiooxamate is a sulfur-containing ester derivative widely used as a key intermediate in pharmaceutical synthesis, particularly for thiazole-containing drugs. The compound exhibits a melting point of 62-65°C (lit.) and boiling point of 199.2±23.0°C at 760 mmHg. With a density of 1.226 g/cm³ (est.) and refractive index of 1.548, it demonstrates moderate solubility in chloroform (25 mg/mL). Storage should be in sealed dark containers at room temperature due to light sensitivity. Safety precautions include wearing protective gloves/eyewear as it may cause skin/eye irritation (GHS Category 2). The thiocarbonyl group enables diverse reactions including cyclocondensations to form heterocyclic scaffolds.
