dithioformate

Dithioformate is an organic compound with the chemical formula H2S2O3. It is a colorless to pale yellow liquid that is miscible with water. The compound is a derivative of sulfuric acid, where two hydroxyl groups have been replaced by sulfur atoms. Dithioformate is a weak acid, with a pKa of approximately 3.5.

The compound is primarily used in the synthesis of other chemicals. It is a precursor to dithiocarbamates, which are used as pesticides and herbicides. Dithioformate is also used in the synthesis of certain dyes and pigments. In the pharmaceutical industry, it is used as a starting material for the synthesis of certain drugs.

Dithioformate is toxic if ingested, inhaled, or absorbed through the skin. It can cause irritation to the eyes, skin, and respiratory system. Prolonged exposure can lead to more serious health effects, including damage to the liver and kidneys. Therefore, handling and storage of dithioformate should be done with appropriate safety measures.

The compound was first synthesized in 1850 by the French chemist Jean-Baptiste Dumas. It was later studied by other chemists, including August Wilhelm von Hofmann, who named the compound dithioformic acid. The name reflects the compound's structure, with two sulfur atoms and a formic acid moiety.
