Formamidine Thiocyanate is a specialty chemical reagent primarily used as an intermediate in organic synthesis for the production of pharmaceuticals, agrochemicals, and fine chemicals. It serves as a building block in the preparation of formamidine derivatives and heterocyclic compounds, such as thiazoles via Hantzsch-type reactions. In research settings, it is applied in medicinal chemistry and biochemical studies for developing novel molecules, though it is not a standard chaotrope for routine RNA or DNA extraction like guanidine salts.
