Thiocarbohydrazide is widely used in analytical chemistry as a reagent for the detection and determination of various metal ions, such as copper, nickel, cobalt, lead, and mercury, due to its strong chelating properties. It is also employed in the synthesis of heterocyclic compounds, which are important in the development of pharmaceuticals and agrochemicals. In the field of photography, thiocarbohydrazide serves as a stabilizer and sensitizer for photographic emulsions, enhancing image quality. Additionally, it is utilized in the production of dyes and pigments, where it acts as an intermediate in the synthesis of complex colorants. Its ability to form stable complexes with metals makes it valuable in corrosion inhibition and as a component in anticorrosive coatings. Furthermore, thiocarbohydrazide finds application in the preparation of polymers and resins, contributing to the development of materials with specific mechanical and thermal properties.
