Ethyl isothiocyanatoacetate is a versatile organosulfur compound widely used as a key intermediate in pesticide synthesis (e.g., nematicides) and pharmaceutical manufacturing. This liquid exhibits a density of 1.171 g/mL at 25°C and boiling point of 215°C (lit.), with a characteristic pungent odor. Its reactive isothiocyanate group enables diverse transformations including cyclization reactions for heterocyclic compounds. The material should be stored under inert atmosphere at 2-8°C, protected from moisture. Safety precautions require acid-resistant PPE due to its lachrymatory effects and potential skin irritation (GHS Category 2). Industrial applications include its use as a chemical modifier for polymers and in peptide coupling reactions.
